    Description

      Over in HBASE-16349, Mikhail Antonov pointed me to the failed TestClusterId in Jenkins 1.3 build.
      I ran the test locally with Java 8 and consistently stumbled over timeout in starting the mini cluster:

      2016-10-13 15:41:05,276 INFO  [RpcServer.FifoWFPBQ.priority.handler=5,queue=1,port=59233] regionserver.RSRpcServices(1620): Open hbase:namespace,,1476398463993.                               7ab1d0b3b7be8b9a7ce9af61c29d5342.
      2016-10-13 15:41:05,277 ERROR [RpcServer.FifoWFPBQ.priority.handler=5,queue=1,port=59233] ipc.RpcServer(2320): Unexpected throwable object
      java.lang.NullPointerException
        at org.apache.hadoop.hbase.regionserver.RSRpcServices.openRegion(RSRpcServices.java:1679)

        at org.apache.hadoop.hbase.ipc.RpcExecutor$Handler.run(RpcExecutor.java:168)
      

      It turned out that htd for hbase:namespace table was null.

      Once the NPE is fixed, the test passes.
