When all data directory volumes pulled out in DataNode, Its better to shutdown.
-------------------------------------------------------------------------------

                 Key: HDFS-1863
                 URL: https://issues.apache.org/jira/browse/HDFS-1863
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: data-node
    Affects Versions: 0.20.1
            Reporter: Brahma
            Priority: Minor


When we pulled out all the data directory volumes in DataNode, 
 it is not shuttingdown. Because of this NameNode is keep selecting this DN also for write.
But datanode is saying 'No available volumes' and throwing exception.

Instead of this, we can shutdown the DataNode.
