Bahram Chehrazy updated HBASE-22361:
------------------------------------
Description:
When the server is being aborted or stopped, the server waits for all online
regions to flush and close. And if a region is at the end of opening process,
the openEventHandler throws an exception. However, it fails to remove that
region from the on-line regions and fails to notify the master. This would
prevent the server shutdown loop to exit.
Similarly, if regions that are being closed fail for any reason, the
closeEventHandler throws, but again, it fails to remove that region from the
on-line list.
