stack commented on HBASE-14361:
-------------------------------

The jmxmetrics is another instance of our registering the mbean with the wrong 
service:

Class Name: Master,sub=Balancer
Object Name: Hadoop:service=DataNode,name=Master,sub=Balancer

See HBASE-14423 for more.

The org.apache.hadoop.hbase.master.procedure.TestWALProcedureStoreOnHDFS fail 
is to be fixed over in HBASE-14362

Looking at hanging tests I also see Failing test : 
org.apache.hadoop.hbase.client.TestSnapshotCloneIndependence Ain't sure what 
that one is about.

Going to commit.

> Over on HBASE-12911 I have a patch that registers Connection instances with 
> the metrics system. In both standalone server and tll client applications, I 
> was surprised to see multiple connection objects showing up that are unused. 
> These are pretty heavy objects, including lots of client threads for the 
> batch pool. We should track these down and remove them -- if they're not some 
> kind of phantom artifacts of my WIP patch over there.
