Koji Noguchi updated PIG-5391:
------------------------------
Attachment: pig-5391-v01.patch
Copying back the original source by comparing
InternalSortedBag&SortedDataBag
and
InternalDistinctBag&DistinctDataBag
I haven't gone through the changes carefully.
This is more for others to point me to right direction. I'm still hoping this
jira to be invalid. Otherwise, this would mean we had this race condition for
years...

> InternalSortedBag and InternalDistinctBag were designed with single-thread
> access in mind (version 0.6) but later added back to SpillableMemoryManager
> for multi-threads access (PIG-2923). Synchronization were added back in
> PIG-3212 and PIG-3466 respectively but it seems like we missed a couple of
> code that original implementation had.
