Charles Connell updated HBASE-29068:
------------------------------------
Description:
If you are running a table with region replicas, the secondary replicas usually
cannot achieve 100% locality. Currently a RegionServer reports two locality
metrics:
* {{percentFilesLocal}}
* {{percentFilesLocalSecondaryRegions}}
Both of these will be less than 100% if region replicas are enabled. The best
we can do is get 100% locality for the primary replicas, but there is currently
no way to see if we've achieved it.
I propose introducing the new metric {{percentFilesLocalPrimaryRegions}}
