Matt McCline updated HIVE-13282:
--------------------------------
Attachment: HIVE-13282.01.patch
Work-In-Progress.
Changed GroupByOperator.process to ignore the tag and just use 0. This is what
was causing the ArrayIndexOutOfBoundsException. Is this the correct solution
here?
Also, experimented with deferring close on the SMBMapJoinOperator and
CommonMergeJoinOperator (Tez) until all the parents have closed. This produces
wrong results for the ORDER BY query (0 instead of 480) and the new GROUP BY
query (0 instead of ???) in tez_smb_1.q
> GroupBy and select operator encounter ArrayIndexOutOfBoundsException
