Zhihong Ted Yu commented on HBASE-4050:
---------------------------------------
As Todd pointed out on dev mailing list, we can be flexible with the class
names for the new metrics classes as long as we try to keep user-facing (JMX)
interfaces the same with those from 0.94.
The new metrics classes should be annotated with @InterfaceAudience.Private
> Update HBase metrics framework to metrics2 framework
