Subject [jira] [Commented] (YARN-1809) Synchronize RM and Generic History Service Web-UIs
Date Wed, 19 Mar 2014 19:21:45 GMT

    [ https://issues.apache.org/jira/browse/YARN-1809?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13940879#comment-13940879
] 

Mayank Bansal commented on YARN-1809:
-------------------------------------

Thanks [~zjshen] for the patch.
Herer are some comments

1. Change name from ApplicationInformationProtocol to like ApplicationBaseProtocol
2. Why we cant have delegationtoken related api's to Base Protocol?
3. ApplicationHistoryClientService -> Why we removing protocol handler? I think we should
keep it as it was.
4. I am not sure why we removed the ApplicationContext, I think ApplicationContext shoule
be retained
    Isn't it that good if we have the following structure
bq . ApplicationBaseProtocol derived by ApplicationContext
Thoughts?
5. There are lot of refactoring in the patch , which is good but we could have seprated in
two JIRAs which will make changes central to specific issue. Thoughts?

> After YARN-953, the web-UI of generic history service is provide more information than
that of RM, the details about app attempt and container. It's good to provide similar web-UIs,
but retrieve the data from separate source, i.e., RM cache and history store respectively.
