Anastasia Braginsky commented on HBASE-18375:
---------------------------------------------
While the chunks are not in the pool, but in MSLAB they are deallocated
> The pool chunks from ChunkCreator are deallocated while in pool because there
> is no reference to them

> Because MSLAB list of chunks was changed to list of chunk IDs, the chunks
> returned back to pool can be deallocated by JVM because there is no reference
> to them. The solution is to protect pool chunks from GC by the strong map of
> ChunkCreator introduced by HBASE-18010. Will prepare the patch today.
