Gary Helmling commented on HBASE-17579:
---------------------------------------

Tested this and it replaces the existing metric key with new metrics using the 
histogram suffixes.  We'll need to add a compatibility shim to get this in to 
1.3.  In addition to the histogram metrics, report the histogram max under the 
old metric key.  This should work for backwards compatibility.

> Backport HBASE-16302 to 1.3.1

> This is a simple enough change to be included in 1.3.1, and replication 
> monitoring essentially breaks without this change.
