Critical Description
Noticed this one yesterday in some testing. PQS clients were getting stuck in a loop trying to find the location of the hbase:meta region, but never actually finding it despite HBase appearing to be 100% healthy.
In PQS:

Best as I can tell so far, this is due to PHOENIX-3126 and PQS not caching UGI instances. hashCode() and equals() on UGI work on references (not on values). I believe the simple fix is to just add some caching of UGI instances for the end-users in PQS.
