Minwoo Kang created HBASE-23968:
-----------------------------------
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.
