Review request for hive, Zoltan Haindrich, Naveen Gangam, and Peter Vary.


Bugs: HIVE-21610
    https://issues.apache.org/jira/browse/HIVE-21610


Repository: hive-git


Description
-------

Because of HIVE-16227 it can happen that a UnionOperator will partially go into the wrong stage, because the currTask is changed, and the UnionOperator is reinitialized in GenMRFileSink1 with the wrong task.
