Andrew Kyle Purtell resolved HBASE-8459.
----------------------------------------
Resolution: Won't Fix
> make online region snapshotting based on region names instead of region
> server names
> ------------------------------------------------------------------------------------
>
> Key: HBASE-8459
> URL: https://issues.apache.org/jira/browse/HBASE-8459
> Project: HBase
> Issue Type: Bug
> Components: snapshots
> Affects Versions: 0.94.6.1, 0.95.0
> Reporter: Jonathan Hsieh
> Priority: Major
>
> Currently, online snapshots assign work by region server. This works when
> regionseveers do not fail or moved regions. In 0.95+, the table locks
> prevent moves while snapshotting is in progress but a failed RS during a
> snapshot may still fail in the verification step. This is because the
> failure would trigger an assignment which may occur after the work for the
> regionserver is determined, leaving some regions unsnapshotted, thus leaving
> it to fail in the verification step.
> If we instead assigned snapshotting work by region name, a moved region could
> be snapshotted by the newly assigned region server.
