> {{MiniDFSCluster}} should implement {{AutoCloseable}} in order to support 
> [try-with-resources|https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html].
>  It will make test code a little cleaner and more reliable.
> Since {{AutoCloseable}} is only in Java 1.7 or later, this can not be 
> backported to Hadoop version prior to 2.7.
