The Connection timeout property was added to the Salesforce plugin properties in the web interface with the default value of 3600 seconds (PLUGIN-1719).

• For accuracy, fixed schema handling for referenced object fields: child fields are explicitly marked as non-nullable, regardless of the schema values in the referenced object.

In earlier versions, when retrieving schema information for fields in referenced objects, such as contact.account_lastmodifieddate, the schema inherits properties from the referenced object, causing incorrect non-nullable assumptions (PLUGIN-1720).

• A retry mechanism was added in the Salesforce batch source and Multi-Source plugins for connection timeout issues (PLUGIN-1706).

The SAP OData plugin (version 0.9.1) is available in the Cloud Data Fusion SAP Hub (all versions) with the following changes:

• Fixed an issue in the SAP OData batch source causing you not to receive a valid error message if the base URL provided is invalid.
• A warning has been added to the log message when you provide a batch size that is larger than the maximum allowed batch size.

Fixed in Cloud Data Fusion 6.9.1:

• For SQL Server replication sources, fixed an issue on the Review assessment page, where SQL Server DATETIME and DATETIME2 columns were shown as mapped to TIMESTAMP columns in BigQuery. This was a UI bug. The replication job mapped the data types to the BigQuery DATETIME type (CDAP-19389).

• For replication jobs, fixed an issue where retries for transient errors from BigQuery might have resulted in data inconsistency (CDAP-20276).

• Fixed an issue where a replication job got stuck in an infinite retry when it failed to process a DDL operation (CDAP-20301).

• When you duplicate a pipeline, Cloud Data Fusion appends _copy to the pipeline name when it opens in the Pipeline Studio. In previous releases, Cloud Data Fusion appended _<v1, v2, v3> to the name (CDAP-20373).

• Fixed the pipeline stage validation API to return unevaluated macro values to prevent secure macros from being returned (CDAP-20430).

• Fixed an issue that sometimes caused pipelines to fail when running pipelines on Dataproc with the following error: Unsupported program type: Spark. The first time a pipeline that only contained actions ran on a newly created or upgraded instance, it succeeded. However, the next pipeline runs, which included sources or sinks, might have failed with this error (CDAP-20431).

• Fixed an issue where the flow control running count metric (system.flowcontrol.running.count) might be stale if no new pipelines or replication jobs were started (CDAP-20458).

• Fixed an issue where executor resource settings are not honored when app.pipeline.overwriteConfig is set (CDAP-20549).

• In the Oracle batch source, the Oracle NUMBER data type defined without precision and scale by default was mapped to Cloud Data Fusion string data type. If these fields were used by an Oracle Sink to insert into a NUMBER data type field in the Oracle table, the pipeline failed due to incompatibility between string and NUMBER type. Now, the Oracle Sink inserts these string types into NUMBER fields in the Oracle table (PLUGIN-1481).

• For Oracle batch sources, fixed an issue that caused the pipeline to fail when there was a TIMESTAMP WITH LOCAL TIME ZONE column set to NULLABLE and the source had values that were NULL(PLUGIN-1494) .

• Fixed an issue where pipelines that had a Database batch source and an Oracle sink that used a connection object (using SYSDBA) to connect to an Oracle database failed to establish a connection to the Oracle database. This was due to a package conflict between the Database batch source and the Oracle sink plugins (PLUGIN-1503).

• Fixed an issue where pipelines failed when the output schema was overridden in certain source plugins. This was because the output schema didn't match the order of the fields from the query. This happened when the pipeline included any of the following batch sources:

• Database

• Oracle

• MySQL

• SQL Server

• PostgreSQL

• DB2

• MariaDB

• Netezza

• Cloud SQL PostgreSQL

• Cloud SQL MySQL

• Teradata

  Pipelines no longer fail when you override the output schema in these source plugins. Cloud Data Fusion uses the name of the field to match the schema of the field in the result set and the field in the output schema {PLUGIN-1512).

• For BigQuery Pushdown, fixed an issue when BigQuery Pushdown was enabled for an existing dataset, the Location where the BigQuery Sink executed jobs was the location specified in the Pushdown configuration, not the BigQuery Dataset location. The configured Location should have only been used when creating resources. Now, if the dataset already exists, the Location for the existing dataset is used (PLUGIN-1513).

• For the Database sink, fixed an issue where the pipeline didn't fail if there was an error writing data to the database. Now, if there is an error writing data to the database, the pipeline fails and no data is written to the database (PLUGIN-1514).

• Fixed an issue that checks GET permission on a namespace which does not exist yet during the namespace creation flow (CDAP-18394).

• Fixed an issue where Dataproc continued running a job when it couldn't communicate with the Cloud Data Fusion instance if the replication job or pipeline was deleted in Cloud Data Fusion (CDAP-20216).

• Fixed an issue that caused pipelines with triggers with runtime arguments to fail after the instance was upgraded to Cloud Data Fusion 6.8.0 and 6.9.0 (CDAP-20568).

• Fixed an issue where arguments set by actions and pipeline triggers don't overwrite runtime arguments. You must add the following runtime argument: system.skip.normal.macro.evaluation=true (CDAP-20597).

• Fixed an issue that caused the Pipeline Studio page to show an incorrect count of triggers (CDAP-20655).

• Fixed an issue that caused the Trigger's Payload Config to be missing in the UI for an upgraded instance (CDAP-20660).

• Fixed bug where initial offset was not considered in Kafka batch source (PLUGIN-1594).

Fixed in 6.8.3:

• Fixed an issue where the event publish feature did not work with RBAC-enabled instances (CDAP-20375).
• Fixed an issue where executor resource settings were not honored when app.pipeline.overwriteConfig was set (CDAP-20549).
• Fixed an issue that caused pipelines with triggers with runtime arguments to fail after the instance was upgraded to Cloud Data Fusion 6.8.0 and later (CDAP-20568).
• Fixed an issue where arguments set by actions and pipeline triggers don't overwrite runtime arguments. You must add the following runtime argument: system.skip.normal.macro.evaluation=true (CDAP-20597).
• Fixed an issue that caused the Studio page to show an incorrect count of triggers (CDAP-20655).
• Fixed an issue that caused the Trigger's Payload Config to be missing in the UI for an upgraded instance (CDAP-20660).
• Fixed an issue in the BigQuery Sink where the absence of an ordering key caused an exception (PLUGIN-1582).
• Fixed an issue where initial offset was not considered in the Kafka Batch Source (PLUGIN-1594).

Cloud Data Fusion version 6.8.2 fixes an issue in Cloud Data Fusion versions 6.8.0 and 6.8.1 that may cause the following error: Unsupported program type: Spark. The first time a pipeline that only contains actions runs on a newly created or upgraded instance, it succeeds. However, following pipeline runs that also include sources or sinks may fail with this error. For updated settings, see Troubleshooting.

In Cloud Data Fusion version 6.8.1, Dataproc clusters no longer require the following OAUTH scope to function: https://www.googleapis.com/auth/cloud-platform.

Oracle plugins version 1.8.6 is available in Cloud Data Fusion versions 6.7.1, 6.7.2, and 6.7.3. Oracle plugins version 1.9.2 is available in Cloud Data Fusion versions 6.8.0 and later. These plugin versions have the following changes:

For the Oracle Batch Source, fixed a backward compatibility issue. In plugin versions 1.8.3, 1.9.0, and earlier, Cloud Data Fusion maps the Oracle NUMBER data type with undefined precision and scale to CDAP decimal(38,0) , which can cause data loss due to rounding errors. In plugin versions 1.8.4, 1.8.5, and 1.9.1, the Oracle NUMBER data type with undefined precision and scale maps to the CDAP string data type by default, which preserves all decimal digits. In versions 1.8.6 and 1.9.2, the Oracle NUMBER data type with undefined precision and scale gets mapped to CDAP string by default and lets you edit the output schema to use the older mapping to decimal(38, 0) data type. For more information, see Oracle batch source plugin converts NUMBER to string (PLUGIN-1535 ).

Fixed in 6.8.1:

• Fixed an issue in instances with role-based access control where deployment and validations failed with read time out error after a short time.

• Fixed an issue that caused replication assessment for Oracle by Datastream to fail when an instance had role-based access control.

• Fixed an issue that allowed reading secure keys in the system namespace with only the Data Fusion Viewer role (datafusion.viewer) or Instance Accessor role (datafusion.accessor). For more information about predefined roles for role-based access control in Cloud Data Fusion, see the Role-based access control (RBAC) overview.

• Fixed an issue where the Replication Source plugin's event reader was not stopped by the Delta worker when there were errors, which caused leakage of the plugin's resources (CDAP-20394).

• Fixed an issue that occurred in certain upgrade scenarios, where pipelines didn't have the Use Connection property set and the UI didn't display a plugin's connection properties, such as Project ID and Service Account Type (CDAP-20392).

• Fixed an issue that caused pipelines to fail if they used a connection property, such as the Service Account JSON property, that used a secure macro with JSON as the value (CDAP-20271).

• For Oracle by Datastream Replication sources, fixed an issue where the Review Assessment page would freeze when a selected or manually-entered table didn't exist in the source database (CDAP-20257).

• For Oracle by Datastream Replication sources, fixed an issue where the Select tables and transformations page failed to load the list of tables and displayed the error deadline exceeded when the source database contained a large number of tables (CDAP-20199).

• Fixed an error in security-enabled instances that caused pipeline launch to fail and return a token expired error when evaluating secure macros in provisioner properties (CDAP-20146).

• For MySQL Replication sources, fixed an issue that caused Replication jobs to fail during the initial snapshot, if the job included a runtime argument with the Debezium property, binary-handling-mode (CDAP-20121).

• For Replication jobs, increased retry duration for API calls to update state/offsets in Replication jobs (CDAP-20028).

• Fixed an issue that prevented upgrades for MySQL and SQL Server Replication jobs in version 6.6.0. Upgrades are supported from version 6.6.0 to 6.7.3 and 6.8.1 (CDAP-19622).

• Fixed upgrades for Oracle by Datastream Replication jobs. You can upgrade Oracle by Datastream Replication jobs from Cloud Data Fusion versions 6.6.0 and 6.7 to version 6.8.1. (CDAP-20013).

Fixed in 6.7.3:

• Fixed an issue that allowed reading secure keys in the system namespace with only the Data Fusion Viewer role (datafusion.viewer) or Instance Accessor role (datafusion.accessor). For more information about predefined roles for role-based access control in Cloud Data Fusion, see the Role-based access control (RBAC) overview.

• Fixed an issue in the BigQuery Replication Target plugin that caused Replication jobs to fail when the BigQuery target table already existed. The new version of the plugin will automatically be used in new Replication jobs (CDAP-19599).

• Fixed an issue that prevented upgrades for MySQL and SQL Server Replication jobs in version 6.6.0. Upgrades are supported from version 6.6.0 to 6.7.3 and 6.8.1 (CDAP-19622).

• Fixed an issue that prevented upgrades for Oracle by Datastream Replication jobs in version 6.6.0. Upgrades are supported from versions 6.6.0 , 6.7.0, 6.7.1, and 6.7.2 to version 6.7.3 (CDAP-20013).

• Fixed an issue that caused pipelines to fail if they used a connection property, such as the Service Account JSON property, which used a secure macro with JSON as the value (CDAP-20271).

• Fixed an issue that occurred in certain upgrade scenarios, where pipelines didn't have the Use Connection property set and the UI didn't display a plugin's connection properties, such as Project ID and Service Account Type (CDAP-20392).

• Fixed an issue where the Replication Source plugin's event reader was not stopped by the Delta worker when there were errors, which caused leakage of the plugin's resources (CDAP-20394).

• Fixed an error in security-enabled instances that caused pipeline launch to fail and return a token expired error when evaluating secure macros in provisioner properties (CDAP-20146).

• In the Oracle Batch Source (version 1.8.4 and earlier), when the source data included fields with the NUMBER data type with undefined precision and scale, Cloud Data Fusion read it as decimal and set the precision to 38 and the scale to 0. If any values in the field had scale other than 0, values were rounded, which could have resulted in data loss. If the scale for this field is overridden in the plugin output schema, the pipeline fails.
  
  In Oracle batch source version 1.8.5, you can edit the scale of the CDAP decimal data type in the output schema. The overridden value is used to map to the Oracle NUMBER data type without failing the pipeline. If there are any numbers present in the fields with a scale greater than the scale defined in the plugin, Cloud Data Fusion rounds the values based on the scale you set in the output schema. For example, if you specify precision=10, scale=3, the value 123.4567 is rounded to 123.457. For more information about setting precision and scale in a plugin, see Changing the precision and scale for decimal fields in the output schema (PLUGIN-1433).

• Improved performance for batch pipelines with MySQL sinks (PLUGIN-1374).

• For Database plugins (version 2.9.3), fixed a security issue where the database username and password were exposed in the logs (CDAP-20235).

Fixed in 6.8.0:

• For custom Dataproc compute profiles, fixed the issue causing the wrong Cloud Storage bucket to be used to stage data. Cloud Data Fusion uses the bucket specified in the custom compute profile.

• Fixed the issue in the BigQuery Replication Target plugin causing Replication jobs to fail when the BigQuery target table already existed. The new version of the plugin is used by default in new Replication jobs. To use the new plugin version in existing jobs, recreate the job.

• Fixed an issue causing the Replication Assessment to get stuck when the Oracle (by Datastream) storage bucket property was empty, or had an invalid bucket name. Cloud Data Fusion returns a 400 error code during assessment when the property is empty or has an invalid bucket name.

• Fixed an issue causing Replication jobs to fail when the source column name didn't comply with BigQuery table naming conventions. In 6.8.0, if a source column name doesn't comply with BigQuery naming conventions, Cloud Data Fusion replaces invalid characters with an underscore, prepends an underscore when the first character is a number, and truncates the name when it exceeds the maximum length.

• In the File batch source, fixed an issue causing Get Schema to appear only when Format was set to delimited. Get Schema appears for all formats.

• Fixed an issue with the output schema when connecting a Splitter transformation with a Joiner transformation.

• Fixed an issue causing imports in the Cloud Data Fusion UI to fail for pipelines exported through the Pipeline Microservices.

• In the Oracle Batch Source, when the source data included fields with the Numeric data type (undefined precision and scale), Cloud Data Fusion set the precision to 38 and the scale to 0. If any values in the field had scale other than 0, Cloud Data Fusion truncated the values, which could have resulted in data loss. If the scale for a field was overridden in the plugin output schema, the pipeline failed. For more information, see the CDAP 6.8.0 bug fixes.

• In the Wrangler transformation, fixed the issue causing the pipeline to not fail when the Error Handling property was set to Fail Pipeline. This happened when an error was returned, but no exception was thrown, and there were 0 records in the output. For example, this happened when one of the directives (such as.parse-as-simple-date) failed because the input data wasn't in the correct format. This fix is not available by default. Instead, contact support if you need this fix for your projects.

• In Wrangler, fixed the issue causing the Wrangler page to get stuck when a BigQuery table name contained non-alphanumeric characters, such as underscores. Wrangler imports BigQuery tables that follow BigQuery table naming conventions.

Fixed in 6.7.2:

• In the BigQuery Sink plugin (version 0.20.3), fixed an issue that caused a NullPointerException error when table metrics were updated or when the output schema was not defined.
• In the Send Email batch pipeline alert, fixed an issue where emails failed to send when the Protocol was set to TLS.
• (Release note added January 5, 2023) In the Cloud Storage Sink and File Sink plugins, fixed an issue that caused Decimal values to be formatted incorrectly.

Fixed in 6.7.1:

• Fixed an issue that created duplicate entries in the file cache map, which resulted in multiple attempts to delete the same cache file.

• Fixed an issue where the Log service left empty folders, which made the mounting of Persistent Disk slow. This caused the Log service not to start in a timely manner.

• Fixed an issue that caused pipelines to take a long time to launch or get stuck. This was linked to I/O throttling that occurred on the underlying Persistent Disk.

• Fixed an issue that caused pipelines to fail when two or more pipelines were scheduled to start simultaneously on a static Dataproc cluster. This was due to a file upload race condition.

• Fixed an issue in flow control that caused Appfabric to return a 5xx error code in rare scenarios, instead of 429 (Too Many Requests Error), if the number of concurrently launching or running pipelines was above certain thresholds.

• Fixed an issue that resulted in an error when a compute profile was exported from the default namespace after switching from a custom namespace.

• Delete, edit, and export no longer appear as operations for pre-configured connections in Cloud Data Fusion. You can view connection details for those connections.

• Fixed an issue when you started a pipeline multiple times, and then stopped the pipeline before it completed, which resulted in the following UI error: Program <program name> is not running.

• Removed verbose logs from the BigQuery client libraries in pipeline logs.

• Fixed an issue that caused the BigQuery Execute action plugin configured with an Encryption Key Name (CMEK) to fail when the SQL query contained DDL Statements.

• In the BigQuery Execute action plugin, added the property Store Results in a BigQuery Table to the UI, which hides the destination table related properties by default.

Fixed in 6.7.0:

• Fixed an issue in the Group By transformation where Longest String and Shortest String aggregators returned an empty string, even when all records contained null values in the specified field. The Group By transformation returns null for empty input.
• Fixed an issue in the Group By transformation that caused the Concat and Concat Distinct aggregate functions to produce incorrect results in some cases.
• Fixed an issue in the Group By transformation that caused the Variance, Variance If, and Standard Deviation aggregate functions to produce incorrect results in some cases.
• In the Oracle and MySQL Batch Source plugins, fixed an issue to treat all timestamps, specifically the ones older than the Gregorian cutover date (October 15, 1582), from the database in Gregorian calendar format.
• Improved the generic Database source plugin to correctly read data when the data type is NUMBER, scale is set, and the data contains integer values.
• Fixed an issue in sources (such as File and Cloud Storage) that resulted in an error if you clicked Get Schema when the source file contained delimiters used in regular expressions, such as "|" or ".". You no longer need to escape delimiters for sources.
• Fixed an issue where Datastore sources read a maximum of 300 records. Datastore sources read all records.
• Fixed an issue in BigQuery sinks where the output table was not partitioned correctly in the following cases:
  • The output table didn't exist.
  • Partitioning type was set to Time.
  • Operation was set to Upsert.
• Fixed an issue that caused pipelines with BigQuery sinks that have input schemas with nested array fields to fail.
• Fixed issues that caused failures when reading maps and named enums from Avro files.

Fixed in 6.6.0:

• Improved instance stability. Fixed a number of system service unavailability cases resulting in the message "Necessary services are experiencing intermittent problems" and API call failures.
• Fixed an issue that caused pipelines to fail when a Database Batch Source included a decimal column with precision greater than 19.
• Fixed an issue that caused pipelines with a Conditional plugin that were running on MapReduce to fail.
• Fixed an issue that caused pipelines with a Conditional plugin and running on Spark to fail.
• Fixed an issue that caused validation to fail for Cloud Storage Multi File Sinks.

Fixed in 6.5.0 preview version (for more information, see the CDAP release note):

• Fixed an issue in Replication that caused jobs to fail if more than 1000 tables were selected for replication.

• Fixed an issue that caused replication jobs to hang when there were too many Delete or DDL events.

• Fixed an issue that caused Wrangler to ignore all the other columns other than the given column when parsing Excel files.

• Fixed Wrangler to fail pipelines upon error. In Wrangler 6.2 and above, there was a backwards-incompatible change where pipelines did not fail if there was an error and instead were marked as completed.

• Improved resilience of TMS.

• Fixed an issue that caused File Source Plugin validation to fail when there was a macro in the Format field.

Fixed in 6.4.1 (for more information, see the CDAP release note):

• Fixed an issue that caused pipelines with aggregations and Decimal fields to fail with an exception.

• Fixed the Join Condition Type so that it is displayed in the Joiner plugin for pipelines that were upgraded from versions before 6.4.0.

• Fixed Wrangler so that pipelines fail when there is an error. In Wrangler 6.2 and above, there was a backwards-incompatible change where pipelines did not fail if there was an error and were instead marked as complete.
