Subject [jira] [Created] (HBASE-9092) OpenRegion could be ignored by mistake
Date Tue, 30 Jul 2013 20:37:50 GMT
Jimmy Xiang created HBASE-9092:

             Summary: OpenRegion could be ignored by mistake
                 Key: HBASE-9092
                 URL: https://issues.apache.org/jira/browse/HBASE-9092
             Project: HBase
          Issue Type: Bug
          Components: Region Assignment
            Reporter: Jimmy Xiang
            Assignee: Jimmy Xiang
            Priority: Minor

Looked into failed test:$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.$hbase-server/721/testReport/org.apache.hadoop.hbase.master/TestAssignmentManagerOnCluster/testOpenFailedUnrecoverable/

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.
