Sergey Shelukhin commented on HBASE-7701:
-----------------------------------------
The server B crashed after putting the info into meta, before updating ZK. In
fact we are in SSH for server B... so it should not be expected
> Opening regions on dead server are not reassigned quickly

> 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
> Assignee: Jimmy Xiang
> Attachments:

>
> 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.
