Subject [jira] [Commented] (YARN-5725) Test uncaught exception in TestContainersMonitorResourceChange.testContainersResourceChange when setting IP and host
Date Tue, 18 Oct 2016 22:54:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5725?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15586937#comment-15586937
] 

Daniel Templeton commented on YARN-5725:
----------------------------------------

If it's a test-only issue, have you look at fixing it at the source by putting something in
that collection so that there isn't an NPE in the first place?

In any case making the code a little more defensive is probably a good thing.
