> Handle RegionAlreadyInTransitionException in AssignmentManager
> --------------------------------------------------------------

> Key: HBASE-4153
> URL: https://issues.apache.org/jira/browse/HBASE-4153
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.92.0
> Reporter: Jean-Daniel Cryans
> Assignee: ramkrishna.s.vasudevan
> Fix For: 0.92.0
>
> Attachments: HBASE-4153_1.patch, HBASE-4153_2.patch
>
>
> Comment from Stack over in HBASE-3741:
> {quote}
> Question: Looking at this patch again, if we throw a
> RegionAlreadyInTransitionException, won't we just assign the region elsewhere
> though RegionAlreadyInTransitionException in at least one case here is saying
> that the region is already open on this regionserver?
> {quote}
> Indeed looking at the code it's going to be handled the same way other
> exceptions are. Need to add special cases for assign and unassign.
