Subject [jira] [Commented] (YARN-867) Isolation of failures in aux services
Date Tue, 10 Sep 2013 19:57:55 GMT

    [ https://issues.apache.org/jira/browse/YARN-867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13763423#comment-13763423
] 

Xuan Gong commented on YARN-867:
--------------------------------

recreate the patch based on the latest trunk, and add new test case to test the logic.
Remove the API onAuxServiceFailure, we already have onContainersCompleted() to take care of
it.

> Today, a malicious application can bring down the NM by sending bad data to a service.
For example, sending data to the ShuffleService such that it results any non-IOException will
cause the NM's async dispatcher to exit as the service's INIT APP event is not handled properly.
