Andrew Purtell updated HBASE-12658:
-----------------------------------
Attachment: HBASE-12658-0.98.patch
Straightforward backport.
All changes are to private interfaces except where HBASE-11992 (backported int
0.98.9) changed o.a.h.h.regionserver.MetricsSource to
LimitedPrivate(REPLICATION). The changes of interest to MetricsSource are the
removal of public static final Strings:

- public static final String SOURCE_LOG_READ_IN_BYTES =
"source.logReadInBytes";
{code}
No method signatures are modified. I don't think this presents a problem but
would like to highlight it for discussion. We could leave the string constants
in place if so.

> Backport HBASE-12574 (Update replication metrics to not do so many map look
> ups) to 0.98. Nice enhancement. It's a refactor so need to check for compat
> issues there, and we need to add Hadoop 1 compat module support.
