> Key: HBASE-5816
> URL: https://issues.apache.org/jira/browse/HBASE-5816
> Project: HBase
> Issue Type: Bug
> Components: master
> Affects Versions: 0.90.6
> Reporter: Maryann Xue
> Attachments: HBASE-5816.patch
>
>
> The first assign thread exits with success after updating the RegionState to
> PENDING_OPEN, while the second assign follows immediately into "assign" and
> fails the RegionState check in setOfflineInZooKeeper(). This causes the
> master to abort.
> In the below case, the two concurrent assigns occurred when AM tried to
> assign a region to a dying/dead RS, and meanwhile the ShutdownServerHandler
> tried to assign this region (from the region plan) spontaneously.
