Harsh J resolved HDFS-1863.
---------------------------

    Resolution: Cannot Reproduce

This doesn't seem to be a problem on 0.23 given Bharath's work (see comments above).

> 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.
