[jira] [Created] (HBASE-18375) The pool chunks from ChunkCreator are deallocated while in pool because there is no reference to them

Anastasia Braginsky created HBASE-18375:
-------------------------------------------

             Summary: The pool chunks from ChunkCreator are deallocated while in pool because there is no reference to them
                 Key: HBASE-18375
                 URL: https://issues.apache.org/jira/browse/HBASE-18375
             Project: HBase
          Issue Type: Sub-task
            Reporter: Anastasia Braginsky


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.
