hi, maralla

why we considered to replace it?

the output of slots command is structured while nodes' is unsure and is mainly for reading i think.
if the slots is fully distributed it is not sure whether nodes command is reliable.

eg.:
master - 0 1464406084408 14 connected 1,3,4,5,6,8192-12287,13223

is it for network transfer reasons?

CLUSTER SLOTS is much slower than CLUSTER NODES in large clusters with many discrete slots.

yeah got it
it is suggested add fully test case which has many seperated slots associated.

@jasonjoo2010 Another user has reported that because redis 3.2.0 changed the return value of cluster slots, corvus@0.2.3 is not able to update its slot information. So using cluster nodes fixed that as a bonus...

Corvus==0.2.3 doesn't support redis 3.2.0 yet
