Subject [jira] [Updated] (YARN-1599) webUI rm.webapp.AppBlock should redirect to a history App page if and when available
Date Thu, 16 Jan 2014 22:51:26 GMT

     [ https://issues.apache.org/jira/browse/YARN-1599?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gera Shegalov updated YARN-1599:
--------------------------------

    Attachment: YARN-1599.v02.patch

Thinking more about it, there is too much redundant clicking on this page. When the app runs,
or there is a post-mortem tracking url, users want to go there in the first place. I suggest
to consider always redirecting to the tracking url if available.

> When the log aggregation is enabled, and the application finishes, our users think that
the AppMaster logs were lost because the link to the AM attempt logs are not updated and result
in HTTP 404. Only tracking URL is updated. In order to have a smoother user experience, we
propose to simply redirect to the new tracking URL when the page with invalid log links is
accessed.
