> Key: HBASE-8500
> URL: https://issues.apache.org/jira/browse/HBASE-8500
> Project: HBase
> Issue Type: Bug
> Components: master
> Affects Versions: 0.89-fb
> Reporter: Rishit Shroff
> Assignee: Rishit Shroff
> Priority: Minor
>
> With the option of blacklisting a region server from getting assigned new
> regions by the master, we need to have a utility which encapsulates this and
> uses it for rolling restart of a hbase cluster. The JIRA is to create a
> utility which restarts a single region server by:
> 1. blacklisting the region server
> 2. moving all the regions one by one
> 3. restart the region server process
> 4. moving all the regions back
> 5. removing the region server from blacklist
> Along with this, the utility should also be able to estimate the total outage
> observed from client perspective.
