bq. Wait, what wasn't committed to the HBase 1.2 branch?

> 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.
