Subject [jira] [Commented] (YARN-3887) Support for changing Application priority during runtime
Date Tue, 04 Aug 2015 03:07:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-3887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14653002#comment-14653002

Rohith Sharma K S commented on YARN-3887:

One comment
# TreeSet will throw NullPointerException while adding/removing null object. Suppose, SchedulintApplicationAttempt
is not created then {{application.getCurrentAppAttempt()}} will be null which would throw
NPE. I think this has to be handled in {{AbstractComparatorOrderingPolicy#removeSchedulableEntity}}
and {{AbstractComparatorOrderingPolicy#addSchedulableEntity}}
