Jason Lowe updated TEZ-3701:
----------------------------
Priority: Blocker (was: Major)
Raising priority since any silent data corruption is catastrophically bad.
[~harishjp] could you elaborate on what versions are affected? Was this a
recently introduced bug or has this been a problem for some time?
> UnorderedPartitionedKVWriter does not wait for submitted tasks to finish
> before finalMerge.
