Ted Yu commented on HBASE-19779:
--------------------------------
This JIRA was raised from the observation of OOME during unit test.
Nothing can be asserted if region server goes down during unit test.
It seems we can reduce the number of iterations for the unit test so that there
is no OOME during the test.
> The chunk encountering the OOM will store in ChunkCreator forever

> no chance to remove the chunk from {{ChunkCreator}} since MSLABimpl have
> missed the id.
