[jira] [Created] (YARN-2766) [JDK 8] TestApplicationHistoryClientService fails

Robert Kanter created YARN-2766:
-----------------------------------

             Summary: [JDK 8] TestApplicationHistoryClientService fails
                 Key: YARN-2766
                 URL: https://issues.apache.org/jira/browse/YARN-2766
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: timelineserver
    Affects Versions: 2.6.0
            Reporter: Robert Kanter
            Assignee: Robert Kanter


{{TestApplicationHistoryClientService.testContainers}} and {{TestApplicationHistoryClientService.testApplicationAttempts}} both fail because the test assertions are assuming a returned Collection is in a certain order.  The collection comes from a HashMap, so the order is not guaranteed, plus, according to [this page|http://docs.oracle.com/javase/8/docs/technotes/guides/collections/changes8.html], there are situations where the iteration order of a HashMap will be different between Java 7 and 8.

We should fix the test code to not assume a specific ordering.
