Duo Zhang updated HBASE-19751:
------------------------------
Attachment: HBASE-19751.patch
Change to use RegionInfo instead of identifier and namespace. Also use
KeyLocker instead of IdLock in RegionGroupingProvider. When fixing the UTs,
also done bunch of warnings cleanup by changing HTableDescriptor and
HRegionInfo to TableDescriptor and RegionInfo.
> Use RegionInfo directly instead of an identifier and a namespace when getting
> WAL

> This is needed for synchronous replication as we need to determine whether a
> region should use the special WAL which writes to two FileSystems.
> But I think it is a general simplification so we can apply it to master and
> branch-2 first.
