> Regions are unexpectedly made offline in certain failure conditions

> Key: HBASE-9480
> URL: https://issues.apache.org/jira/browse/HBASE-9480
> Project: HBase
> Issue Type: Bug
> Reporter: Devaraj Das
> Priority: Blocker
> Fix For: 0.96.0
>
> Attachments: 9480-1.txt, trunk-9480.patch
>
>
> Came across this issue (HBASE-9338 test):
> 1. Client issues a request to move a region from ServerA to ServerB
> 2. ServerA is compacting that region and doesn't close region immediately. In
> fact, it takes a while to complete the request.
> 3. The master in the meantime, sends another close request.
> 4. ServerA sends it a NotServingRegionException
> 5. Master handles the exception, deletes the znode, and invokes regionOffline
> for the said region.
> 6. ServerA fails to operate on ZK in the CloseRegionHandler since the node is
> deleted.
> The region is permanently offline.
> There are potentially other situations where when a RegionServer is offline
> and the client asks for a region move off from that server, the master makes
> the region offline.
