> RegionMover should deal with unknown (split/merged) regions

> Key: HBASE-24795
> URL: https://issues.apache.org/jira/browse/HBASE-24795
> Project: HBase
> Issue Type: Improvement
> Reporter: Viraj Jasani
> Assignee: Viraj Jasani
> Priority: Major
> Fix For: 3.0.0-alpha-1, 2.3.1, 2.4.0
>
>
> For a cluster with very high load, it is quite common to see flush/compaction
> happening every minute on each RegionServer. And we have quite high chances
> of multiple regions going through splitting/merging.
> RegionMover, while unloading all regions (graceful stop), writes down all
> regions to a local file and while loading them back (graceful start), ensures
> to bring every single region back from other RSs. While loading regions back,
> even if a single region can't be moved back, RegionMover considers load()
> failure. We miss out on possibilities of some regions going through
> split/merge process and the fact that not all regions written to local file
> might even exist anymore. Hence, RegionMover should gracefully handle moving
> any unknown region without marking load() failed.
