getMasterStats problems
I'm trying to get the master stats in the same way the monitor server
does, but I keep having issues.

The code I'm using is from the GetMasterStats.java program:

    MasterClientService.Iface client = null;
    MasterMonitorInfo stats = null;
    try {
      client = MasterClient.getConnectionWithRetry(HdfsZooInstance.getInstance());
      stats = client.getMasterStats(null,
SecurityConstants.getSystemCredentials());
    } finally {
      if (client != null)
        MasterClient.close(client);
    }

The problem is that the HdfsZooInstance can never find the instance
data, even though it's there. I can create a ZooKeeperInstance just
fine, but passing that into the MasterClient fails the same way.

Caused by: java.lang.RuntimeException: Accumulo not initialized, there
is no instance id at /accumulo/instance_id

... 91 more

Any ideas as to what I'm missing?
