> 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.
