Enis Soztutar commented on PHOENIX-3062:
----------------------------------------
Checked the patch, seems the right approach.
You should also delete PhoenixMetricsSink since it is not needed anymore. Also
rename TraceMetricSource because it is not a MetricSource anymore.
There is a couple of debug statements lying around.

> With some recent fixes in the hbase metrics system, we are now affectively
> restarting the metrics system (in HBase-1.3.0, probably not affecting 1.2.0).
> Since we use a custom sink in the PhoenixTracingEndToEndIT, restarting the
> metrics system loses the registered sink thus causing a hang.
> We need a fix in HBase, and Phoenix so that we will not restart the metrics
> during tests.
> Thanks to [~sergey.soldatov] for analyzing the initial root cause of the
> hang.
> See HBASE-14166 and others.
