Subject [jira] [Commented] (YARN-4994) Use MiniYARNCluster with try-with-resources in tests
Date Tue, 03 May 2016 08:45:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-4994?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15268376#comment-15268376

John Zhuge commented on YARN-4994:
----------------------------------

bq. Last week I created a new JIRA ticket to follow up this. Please check YARN-5007. Is it
fine with you if I resolve it with the ticket I linked?
Good plan.

Unit test failures may be unrelated. To be sure, run the same tests on a clean tree before
your patch. BTW, I do hit test errors in TestYarnClient, TestGetGroups, and TestAMRMProxy
on Ubuntu 14.04.

> 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 since Java7 instead of the pattern above.
