Lars Hofhansl resolved HBASE-1406.
    Resolution: Won't Fix

Doesn't look like this is going to happen.

> Refactor HRS
> ------------
>                 Key: HBASE-1406
>                 URL: https://issues.apache.org/jira/browse/HBASE-1406
>             Project: HBase
>          Issue Type: Improvement
>          Components: regionserver
>    Affects Versions: 0.20.0
>            Reporter: Nitay Joffe
> The current HRS implementation is a mess, especially after ZooKeeper additions to handle
Session Expired events. See HBASE-1311.
> It contains logic to restart itself which caused a lot of fields to be non-final that
can be. It should be split out to two separate class, one that runs HRS duties and one that
watches over the first in a join/restart loop. Using this means a special event like a ZooKeeper
Session Expired wouldn't require special restart code, just an abort. The new wrapper class
will handle restarting.
