Date Wed, 18 Dec 2013 18:22:07 GMT
Jean-Marc Spaggiari created HBASE-10199:
-------------------------------------------

             Summary: Improve rolling restart latency
                 Key: HBASE-10199
                 URL: https://issues.apache.org/jira/browse/HBASE-10199
             Project: HBase
          Issue Type: Improvement
          Components: scripts
    Affects Versions: 0.94.14, 0.98.1, 0.99.0, 0.96.1.1
            Reporter: Jean-Marc Spaggiari
            Assignee: Jean-Marc Spaggiari


HBASE-10049 introduced a 20 seconds delay in the region_mover script to make sure server is
online before starting the transfer. On big cluster, this can add more than 1 hour to the
total time. We need to find a way to make 100% sure the server is online without having to
wait for those 20 seconds.
