-----------------------------------

             Summary: Periodically check whether a system stop is requested in compaction.
                 Key: HBASE-23968
                 URL: https://issues.apache.org/jira/browse/HBASE-23968
             Project: HBase
          Issue Type: Bug
          Components: Compaction
            Reporter: Minwoo Kang
            Assignee: Minwoo Kang


The compaction check that the system is stopped when it reaches hbase.hstore.close.check.interval size.
If the size is not reached, the compaction does not stop even though the system is stopped.
If compaction is not terminated, the region is not closed.
As a result, region remains pending-close.
