No longer an issue on trunk after the shell changes.

org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /user/test/foo._COPYING_
could only be replicated to 0 nodes instead of minReplication (=1).  There are 2 datanode(s)
running and 2 node(s) are excluded in this operation.

> The process of putting file into dfs is approximately as follows:
> 1) create a file in the dfs
> 2) copy from one stream to the file
> But the problem is that the file is still retained in the dfs when the process 2) is
terminated abnormally with unexpected exceptions,such as there is no DataNode alive.
