-----------------------------------
njain has commented on the revision "HIVE-3536 [jira] Output of sort merge join
is no longer bucketed".
Otherwise, it looks good
INLINE COMMENTS
ql/src/test/queries/clientpositive/smb_mapjoin_11.q:32 Unfortunately, this
does not verify that the data is bucketed.
Can you perform a join between test_table3 and test_table1 for bucket 2 for
both of them.
That would return 0 rows if the data was not bucketed correctly.

> Key: HIVE-3536

> Project: Hive
> Issue Type: Bug

> I don't know if this was a feature or a happy coincidence, but before
> HIVE-3230, the output of a sort merge join on two partitions would be
> bucketed, even if hive.enforce.bucketing was set to false. This could
> potentially save a reduce phase when inserting into a bucketed table.
> This would be good to have back.
