>                 Key: HBASE-13682
>                 URL: https://issues.apache.org/jira/browse/HBASE-13682
>             Project: HBase
>          Issue Type: Bug
>          Components: Balancer
>            Reporter: Elliott Neil Clark
>            Priority: Major
>
> Right now when the balancer needs to know about region locality it asks the cache in serial. When the cache is empty or expired it goes to the NN.
> On larger clusters with lots of blocks this can be really slow. That means that balancer is un-usable while masters are being restarted.
