Subject [jira] [Commented] (YARN-867) Isolation of failures in aux services
Date Fri, 04 Oct 2013 16:21:42 GMT

    [ https://issues.apache.org/jira/browse/YARN-867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13786288#comment-13786288

Alejandro Abdelnur commented on YARN-867:
-----------------------------------------

patch6 does not look good to me, the try/catch are not correct as an exception in ANY auxiliary
service will halt delivery to the other auxiliary services. the try/catch should be done around
each call to the auxiliary service interface methods as done in patch4.

> 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.
