    Description

      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.
