> 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
> Attachments: 3866-max-regions-per-iteration.patch, slow_balancer.rb,
> slow_balancer.rb
>
>
> 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.
