Rohini Palaniswamy updated PIG-5327:
------------------------------------
Description:
The killJob is invokedby
- grunt kill command
- thread interrupt in Main (mostly in case of Oozie)
- HangingJobKiller during shutdown
killJob tries to kill the DAG again even if it was completed. It closes the
session but does not remove it from the TezSessionManager session pool. Though
both of these are minor issues and have no adverse impact (trying to kill a
done DAG would be ignored by Tez AM and TezSessionManager would later check
status of the session and remove it from the pool) the fix would avoid the two
unnecessary calls to AM.
