Anastasia Braginsky commented on HBASE-18375:
---------------------------------------------

bq. +1 to fix there as well.
How do you think it should be fixed there? Separate JIRA? Separate patch?

In anyway, [~anoop.hbase], [~ram_krish], [~eshcar] please review the patch I 
have uploaded 2 days ago (here and on RB). 
So we can promote the fix at least in the master.
Thanks!!!

> 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.
