Subject [jira] [Commented] (YARN-5382) RM does not audit log kill request for active applications
Date Fri, 22 Jul 2016 05:39:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15388954#comment-15388954

Sunil G commented on YARN-5382:
-------------------------------

Hi [~vrushalic]
Thanks for updating the patch. I think there is a slight misunderstanding, I guess my comment
was not very clear. What I was trying convey is that If we choose to use {{RMAppKillEvent}}
for all cases, I think for internal kill events (within scheduler such as {{AbstractYarnScheduler}}
and {{CapacityScheduler}}) we do not need to do audit logging. So we can either pass a flag
to log or can pass username/ip as empty to take the logging decision.

I think for internal scheduler kill events, we will not be able to derive username or remote
ip correctly as its not user driven. Thoughts?

> ClientRMService will audit a kill request but only if it either fails to issue the kill
or if the kill is sent to an already finished application.  It does not create a log entry
when the application is active which is arguably the most important case to audit.
