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

             Summary: Better the Assignment plan when server aborted or creating tables, etc.
                 Key: HBASE-17159
                 URL: https://issues.apache.org/jira/browse/HBASE-17159
             Project: HBase
          Issue Type: New Feature
          Components: Balancer, Region Assignment
    Affects Versions: 1.2.4, 2.0.0
            Reporter: Charlie Qiangeng Xu


When master processing a dead serve or creating a new table, the assignment plan would be
generated based on the roundRobinAssignment method of balancer.
Yet if these operations happen a lot, the cluster would be out of balance both on table level
and server level. Balancer would be triggered and may cause huge amount of region moves( This
is what we observed).
Ideally, the assignment should be able to consider the table or cluster level balance as well
as locality(for the case of dead server).
