Subject [jira] [Commented] (YARN-6871) Add additional deSelects params in getAppReport
Date Mon, 07 Aug 2017 06:10:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16116105#comment-16116105

Tanuj Nayak commented on YARN-6871:
-----------------------------------

Hey [~sunilg], regarding the second point, the resource request assignment was originally
done within another if clause controlled by the hasAccess variable. Moving the check on this
assignment down would mean moving it out of this if clause. Is it fine if that happens?

> This jira tracks the effort to add additional deSelect params to the GetAppReport to
make it lighter and faster.
> With the current one we are facing a scalability issues.
> E.g. with ~500 applications running the AppReport can reach up to 300MB in size due to
the {{ResourceRequest}} in the {{AppInfo}}.
> Yarn RM will return the new result faster and it will use less compute cycles to create
the report and it will improve the YARN RM and Client's performances.
