Andrew Kyle Purtell resolved HBASE-17159.
-----------------------------------------
Resolution: Abandoned
> Improve 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
> Priority: Major
>
> 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).
