Siddharth Seth commented on HIVE-14111:
---------------------------------------
FileSinkOperator, Operation, MetadataOperation, SQLOperation changes carried
forward from some other patch ?
The try { } finally {} in TezTask needs to deal with one special condition. An
attempt to submit() dag can result in session.destroy being invoked - in which
case I believe the session is lost again, and will never be added back to the
queue.
Also - while going through this code, I noticed some other interesting bits.
Will post that as a diff - let me know what you think. Definitely seems like a
part2 will be required, and unit tests.
> better concurrency handling for TezSessionState - part I
