Andrew Purtell commented on HBASE-12361:
----------------------------------------
The patch is low risk, but we already expose locality information via metrics.
I'm wondering what advantage there is to showing it in the UI? It does add a
new float to ClusterStatus, which I think we would like to ultimately do away
with, so moves us in the wrong direction in that sense. That said if there's a
good case for how the updated information in the UI would be used I have no
objection.
