Subject [jira] [Commented] (YARN-2928) Application Timeline Server (ATS) next gen: phase 1
Date Sat, 31 Jan 2015 01:30:38 GMT

    [ https://issues.apache.org/jira/browse/YARN-2928?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14299530#comment-14299530
] 

Robert Kanter commented on YARN-2928:
-------------------------------------

To mirror my comment from the doc that Sangjin is referring to; I had said:
{quote}It would be useful to be able to aggregate to queues; what would be a good way to fit
those into the data model?{quote}
in the "Some issues to address" section.

As discussed, if we only do child --> parent aggregation ("primary aggregation"), then
we can't aggregate to queues because they don't really fit in that path.

> We have the application timeline server implemented in yarn per YARN-1530 and YARN-321.
Although it is a great feature, we have recognized several critical issues and features that
need to be addressed.
> This JIRA proposes the design and implementation changes to address those. This is phase
1 of this effort.
