    Description

      Trying to do a controlled shutdown of hbase, the RPC Server spews the following ugly output:

      unknown-208-76-47-46:~/Documents/checkouts/hadoop-trunk stack$ ./src/contrib/hbase/bin/hbase master stop
      07/05/24 12:53:47 INFO ipc.Server: Stopping server on 60000

      You get the same noise when if run the TestIPC unit test.
