[jira] [Created] (HBASE-8467) [89-fb] Add an option to blacklist a region server

------------------------------------

             Summary: [89-fb] Add an option to blacklist a region server
                 Key: HBASE-8467
                 URL: https://issues.apache.org/jira/browse/HBASE-8467
             Project: HBase
          Issue Type: Bug
          Components: master
    Affects Versions: 0.89-fb
            Reporter: Rishit Shroff
            Priority: Minor


Add an API to blacklist a region server. The master should not assign any new regions to the blacklisted region server. This will help in Rolling Restart of HBase, where one can blacklist a regionserver, drain all the regions(which should be fast), restart the regionserver, assign the regions backs and then remove the region server from the blacklist
