Subject [jira] [Updated] (YARN-2766) [JDK 8] TestApplicationHistoryClientService fails
Date Wed, 29 Oct 2014 05:02:33 GMT

Robert Kanter updated YARN-2766:
    Attachment: YARN-2766.patch

The patch creates a consistent ordering by sorting the Collection before the assert statements.
 There was similar code in {{testApplications}} so I sorted there as well just in case.

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