Andras Bokor updated YARN-4994:
-------------------------------
Description:
In tests MiniYARNCluster is used with the following pattern:
In try-catch block create a MiniYARNCluster instance and in finally block close
it.
[try-with-resources|https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html]
is preferred from Java7 instead of the pattern above.
was:
{{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.
> Use MiniYARNCluster with try-with-resources in tests
