Michael Smith closed IMPALA-13532.
----------------------------------
Resolution: Fixed
Decided to go a different route for the moment as BufferedTupleStream would
need a number of changes: full multi-threading and the ability to release
fully-processed chunks.
> Add concurrent unpinned reader support to BufferedTupleStream

> Project: IMPALA
> Issue Type: Sub-task
> Components: Backend
> Reporter: Michael Smith
> Assignee: Michael Smith
> Priority: Major
>
> Modify BufferedTupleStream to support multiple concurrent unpinned readers.
> Currently it requires the buffer to be pinned to support concurrent readers.
> This primarily involves additional locking around pinning/unpinning to ensure
> concurrent readers don't cause conflicts.
