metrics sink! No TraceMetricsSink found on the classpath

> Reporter: ryang-sfdc

> Labels: enhancement

> I'd like to know how much cpu, physical io, logical io, wait time, blocking
> time, transmission time was spent for each thread of execution across the
> hbase cluster, within coprocessors, and within the client's phoenix
> threadpools for each query.
> Here are some of the problems I want to solve:
> 1) every component has one or more configurable threadpools, and I have no
> idea how to gather data to make any decisions.
> 2) queries that I think should be fast turn out to be dog slow, e.g., select
> foo from bar where foo like 'abc%' group by foo Without attaching a profiler
> to hbase, which most people won't bother with, it's not clear why it's slow.
