Script to add regions gradually to a new regionserver.
------------------------------------------------------

                 Key: HBASE-3866
                 URL: https://issues.apache.org/jira/browse/HBASE-3866
             Project: HBase
          Issue Type: Improvement
          Components: scripts
    Affects Versions: 0.90.2
            Reporter: Aravind Gottipati
            Priority: Minor


When a new region server is brought online, the current balancer kicks off a 
whole bunch of region moves and causes a lot of regions to be un-available 
right away.  A slower balancer that gradually balances the cluster is probably 
a good script to have.  I have an initial version that mooches off the 
region_mover script to do this.
