[jira] [Updated] (HBASE-7701) inconsistent state in
AssignmentManager for moving region
[ https://issues.apache.org/jira/browse/HBASE-7701?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sergey Shelukhin updated HBASE-7701:
------------------------------------
Affects Version/s: 0.96.0
> inconsistent state in AssignmentManager for moving region
> ---------------------------------------------------------
>
> Key: HBASE-7701
> URL: https://issues.apache.org/jira/browse/HBASE-7701
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.96.0
> Reporter: Sergey Shelukhin
>
> Closed regions are not removed from assignments. I am not sure if it's a general state problem, or just a small bug; for now, one manifestation is that moved region is ignored by SSH of the target server if target server dies before updating ZK.
