> 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.
