Subject CubeVisitService AggregateRegionObserver prevent RegionServer Startup
Date Wed, 29 Jun 2016 13:40:33 GMT
I had a problem that required moving a NamedNode to another machine.  After the move, I immediately
started having issues with HBase Region Servers not starting.  There are issues with CubeVisitService
and AggregateRegionObserver still trying to connect to the old named Node.

I am using HBase 1.1 on HDP 2.4
Is there a way to correct this, or am I going to have to delete the contents of hbase?
