Subject [jira] [Updated] (HBASE-9092) OpenRegion could be ignored by mistake
Date Wed, 31 Jul 2013 00:01:48 GMT

     [ https://issues.apache.org/jira/browse/HBASE-9092?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jimmy Xiang updated HBASE-9092:
-------------------------------

    Fix Version/s: 0.95.2
                   0.98.0
           Status: Patch Available  (was: Open)

Attached a patch that sending a closing region to the server before trying to open the region
again after it's moved to failed_open state.  By that way, the region won't be opening on
the region server any more.

> Looked into failed test: http://54.241.6.143/job/HBase-0.95/org.apache.hbase$hbase-server/721/testReport/
> In this test run, several tests in TestAssignmentManagerOnCluster failed.  Most of them
timed out because the first failure testOpenFailedUnrecoverable used too much resource in
deleting the table.

> The reason testOpenFailedUnrecoverable failed is that the second openRegion call was
ignored since the previous open call was still going on and stayed in OpenRegionHandler#doCleanUpOnFailedOpen
for too long (perhaps thread scheduling issue).  The second openRegion call was skipped since
the region was still in the middle of opening.  However, the failed_open event was already
processed by master.  Therefore the region stuck in transition and the delete table went no
where.  It is a similar issue as we ran into before while for that time, the region was closing.
