Subject [jira] [Commented] (YARN-3661) Basic Federation UI
Date Wed, 20 Sep 2017 19:00:03 GMT

    [ https://issues.apache.org/jira/browse/YARN-3661?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16173679#comment-16173679
] 

Carlo Curino commented on YARN-3661:
------------------------------------

[~elgoiri] and [~giovanni.fumarola] for the contribution/reviews. A few more nits trying this
in a test cluster:
# The columns in "federation" tab for applications could be confusing because their sum would
double-count. Please add a * comment that warns the user that the counts are "local" to each
RM and should not be added.
# For the about page I would put a N/A (until we improve the  REST endpoint to support unique
app counts)
# Links in Application is busted, "State" is busted

> 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.
