----------------------------------

             Summary: Use MiniYARNCluster with try-with-resources in tests
                 Key: YARN-4994
                 URL: https://issues.apache.org/jira/browse/YARN-4994
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: test
    Affects Versions: 2.7.0
            Reporter: Andras Bokor
            Priority: Trivial
             Fix For: 2.7.0


{{MiniYARNCluster}} 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.
