Subject [jira] [Commented] (YARN-5028) RMStateStore should trim down app state for completed applications
Date Thu, 01 Mar 2018 15:02:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-5028?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16382113#comment-16382113

Gergo Repas commented on YARN-5028:
-----------------------------------

[~rohithsharma] Apologies for causing the break, and thanks for the addendum patch! The addendum
patch looks good to me.

(I'm also fine with having my change reverted, and adding it back later after I tested it
with ATSv2, even if it's for a later release).

> RMStateStore stores enough information to recover applications in case of a restart.
The store also retains this information for completed applications to serve their status to
REST, WebUI, Java and CLI clients. We don't need all the information we store today to serve
application status; for instance, we don't need the {{ApplicationSubmissionContext}}.
