------------------------------------
Component/s: dfs
> Calling DFSClient.close() should not throw IOException when it is already
> closed.

> Key: HADOOP-2998

>
> In Java, if a stream is opened, it can be closed for more than one times
> without any exception. For example,
> {code}
> OutputStream out = ...;
> ...
> out.close();
> out.close(); //no exception thrown here
> {code}
> So, DFSClient.close() should also do the same.
