Subject [jira] [Commented] (YARN-3603) Application Attempts page confusing
Date Wed, 23 Sep 2015 18:05:04 GMT

    [ https://issues.apache.org/jira/browse/YARN-3603?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14904945#comment-14904945

Sunil G commented on YARN-3603:

Hi [~jeffzhang]
Thank you for sharing the thoughts. I could remember an old JIRA YARN-1809, where UI is made
similar for RM and HistoryServer.
Here we use {{getContainers)), where History/Timeline fills containers info from ApplicationContext
(has all container info). But RM was taking from RMContext where only live containers are
taken. I understood the need of killed containers here. it can help in debugging. However
we have to segregate killed/preempted containers from completed containers. 

Hi [~leftnoteasy]
I also feel that we can have the information about killed/preempted container along with running
containers in app attempt UI. In YARN-1809, we added for only running containers. Could you
pls share your thoughts here.

> The application attempts page (http://RM:8088/cluster/appattempt/appattempt_1431101480046_0003_000001)
> is a bit confusing on what is going on.  I think the table of containers there is for
only Running containers and when the app is completed or killed its empty.  The table should
have a label on it stating so.  
> Also the "AM Container" field is a link when running but not when its killed.  That might
be confusing.
> There is no link to the logs in this page but there is in the app attempt table when
looking at http://
