Duo Zhang commented on HBASE-21965:
-----------------------------------
Obviously there are problems in MasterRpcServices.checkRegionStillProblematic.
We use an iterator for problemRegions, and then in the loop, we use
problemRegions.remove to remove entries.
And why is the enum name in lower case? It is an anti pattern.
Let me revert the patch here first, too many problems. Please fix these
problems and then commit again.
Thanks. [~tianjingyun] [~zghaobac].
