Subject [jira] [Commented] (YARN-2928) Application Timeline Server (ATS) next gen: phase 1
Date Sat, 07 Feb 2015 00:23:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-2928?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14310286#comment-14310286
] 

Hitesh Shah commented on YARN-2928:
-----------------------------------

Also, what if an application does not want to write data to ATS or does not care if the data
does not reach ATS?  Will there now be more flags introducing an application submission to
tell the RM that it does or does not need the ATS service so as to ensure that its app does
not fail?

> 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.
