Subject [jira] [Commented] (YARN-5743) [Atsv2] Publish queue name and RMAppMetrics to ATS
Date Tue, 18 Oct 2016 16:35:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5743?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15585928#comment-15585928

Varun Saxena commented on YARN-5743:

bq. Diagnostic report is for per node basis. This will over spam the application storage.

That's true. Agree with you.

bq. aggregated log will be deleted after some time as per configuration configured. Since
we are storing very long history of applications, very old applications logs might be deleted
which gives wrong information to reader.
I do not think it will give wrong information to reader because its just saying whether log
aggregation had succeeded or failed. Deletion of aggregated logs is a separate functionality
which admins would be knowing about. 
I just thought about this because for some applications which may have failed in last 3-4
days, we may look for their logs and if some logs were missing, log aggregation status and
diagnostics info may have been useful. But without diagnostic info, we may not get much info
on what went wrong anyways. Also, log aggregation status will not be immediately available
i.e. when finished event is published. So even if we do publish it, we can probably handle
it in a different JIRA.
[~sjlee0], your thoughts on this ?

> App queue name is missed to publish to ATSv2. 
> And RMAppMetrcs publish only cpu and memory. There are many more things to publish from
app metrics such as 
>  resourcePreempted;
>  numNonAMContainersPreempted;
> numAMContainersPreempted.
> And RMAppMetrics need to be published to App metrics rather than info.
