Subject [jira] [Commented] (YARN-254) Update fair scheduler web UI for hierarchical queues
Date Wed, 19 Dec 2012 03:02:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-254?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13535604#comment-13535604

Alejandro Abdelnur commented on YARN-254:
-----------------------------------------

+1. I've applied the patch to trunk, built and installed a speudo cluster, configure fair
scheduler and define a few nested queues, started the cluster, submitted a job to a nested
queue and verified visualization is of hierarchical queues works as advertised. Thanks Sandy,
as a follow up JIRA we should make sure the tree expansion remains the same on browser refreshes,
we could accomplish that encoding the current expansion in a cookie, thus not keeping any
state in the RM.

nested queues.
