----------------------------------------------

Thanks [~yuzhih...@gmail.com]

Patch HBASE-20001.branch-1.4.005.patch passed precommit tests (failure 
unrelated) and is ready for review.

I can post patches for other branches if the 1.4 one looks ok.

> cleanIfNoMetaEntry() uses encoded instead of region name to lookup region

> In RegionStates.cleanIfNoMetaEntry()

> hri.getEncodedNameAsBytes()) == null) {}}
> {{regionOffline(hri);}}
> {{FSUtils.deleteRegionDir(server.getConfiguration(), hri);}}

> But api expects regionname
> {{public static Pair<HRegionInfo, ServerName> getRegion(Connection 
> connection, byte [] regionName)}}
> So we might end up cleaning good regions.
