------------------------------------
That's the region stuck in transition:

regionserver.HRegionServer(3468): Receiving OPEN for the
region:testOpenFailedUnrecoverable,A,1375188570630.e760841b763bd2e8e453af3b6c7c7b6b.
, which we are already trying to OPEN - ignoring this new request for this
region.

> Project: HBase
> Issue Type: Bug
> Components: Region Assignment
> Reporter: Jimmy Xiang
> Assignee: Jimmy Xiang
> Priority: Minor
>
> 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.
