Sergey Shelukhin updated HIVE-16761:
------------------------------------
Attachment: HIVE-16761.patch
The fix to get a correct MapWork for multi-input cases. If one MapWork has
several root operators, that would throw an exception elsewhere. Will test
again on the query, I've tested a slightly different patch just now and it
fixes the issue, this one should too.
