Subject [jira] [Commented] (YARN-3250) Support admin/user cli interface in for Application Priority
Date Thu, 30 Jul 2015 11:48:04 GMT

    [ https://issues.apache.org/jira/browse/YARN-3250?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14647507#comment-14647507

Rohith Sharma K S commented on YARN-3250:

bq. I think one problem is that if there's ever a value set in state-store, RM cannot pick
up the value using the config any more
I see, I agree. configuration files would become stale after one restart/switch. How about
having command that read yarn-site.xml specific configurations very likely similar to {{./yarn
rmadmin refreshAdminAcls}}.This read *yarn.admin.acl* from yarn-site.xml configuration when
refreshAdminAcls invoked. Similar line, setting cluster-max-application-priorty would be {{./yarn
rmadmin refreshClusterMaxPriority}} or {{./yarn rmadmin refreshClusterPriority}}. Thoughts?

bq. How about yarn application <ApplicationId> -setPriority <priority> ?
Make sense.

> Current Application Priority Manager supports only configuration via file. 
> To support runtime configurations for admin cli and REST, a common management interface
has to be added which can be shared with NodeLabelsManager.
