Subject [jira] [Commented] (YARN-3661) Basic Federation UI
Date Fri, 15 Sep 2017 17:55:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-3661?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16168261#comment-16168261

Giovanni Matteo Fumarola commented on YARN-3661:
------------------------------------------------

The code looks good to me. I had an offline meeting with [~elgoiri] in which he showed the
new UI from Router. It has 4 views:
* The current status of all the SubClusters. If Federation is not enabled, the page is not
enabled.
* The aggregations of all the Metrics.
* All the applications in the entire Federated cluster.
* All the nodes in the entire Federated cluster.

> The UIs provided by each RM, provide a correct "local" view of what is running in a sub-cluster.
In the context of federation we need new 
> UIs that can track load, jobs, users across sub-clusters.
