Looking at [1], specifically the overview section, I think they are the
same metrics just accessible via JMX instead of configuring a sink.

Re: Hadoop Metrics2 and JMX

I don't think we're doing anything special to publish to JMX. I think this
is something that is a feature of Hadoop Metrics2 that we're simply
enabling. So, this might be a question for the Hadoop general mailing list
if nobody knows the answer here.
