Review Comment:
in case of keygen not set or NonpartitionedKeyGenerator,
`partitionColumns.mkString(",")` still make sense. what does this change fix?
besides, we should do config validation instead of fixing the logic here, for
e.g., when keygen is non partitioned, partition field should not be non-empty.
