      Description

      Title: Some code level logical issues.

      Description:

      1. DFSClient:
      Consider the below case, if we enable only info, then below log will never be logged.
      if (ClientDatanodeProtocol.LOG.isDebugEnabled())

      { ClientDatanodeProtocol.LOG.info("ClientDatanodeProtocol addr=" + addr); }

      2.org.apache.hadoop.hdfs.server.namenode.FSNamesystem.registerMBean()

      catch (NotCompliantMBeanException e)

      { e.printStackTrace(); }

      We can avoid using stackTace(). Better to add log message.

          For the log message for ClientDatanodeProtocol, I think it's better to change the log to Debug level, rather than change the guard. It's not that useful of a log message to be set at INFO level.
