> 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.
> 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.
