Subject [jira] [Commented] (YARN-2995) Enhance UI to show cluster resource utilization of various container types
Date Thu, 03 Nov 2016 22:31:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-2995?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15634527#comment-15634527

Konstantinos Karanasos commented on YARN-2995:

Regarding the remaining issues:
* The checkstyle issue is about a method that takes more than 7 parameters in one of the test
classes. That was already the case for that method; I just added some more parameters.
* The javadoc issue, as I already explained in a comment above, is related to Java 8 complaining
about using '_' as identifiers. This is used in multiple places in the Web UI classes, and
should be treated in a separate JIRA.
* The unit test issue regarding {{TestQueuingContainerManager}} is unrelated to the present
JIRA and is tracked in YARN-5377.
* There is a build issue in sls when running the corresponding tests, but it might be a Jenkins
issue, since it builds fine for me locally. Just kicked-off Jenkins again to see if the problem

> This JIRA proposes to extend the Resource manager UI to show how cluster resources are
being used to run *guaranteed start* and *queueable* containers.  For example, a graph that
shows over time, the fraction of  running containers that are *guaranteed start* and the fraction
of running containers that are *queueable*.
