Subject [jira] [Updated] (MAPREDUCE-3174) app master UI goes away when app finishes - not very user friendly
Date Thu, 13 Oct 2011 10:25:11 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3174?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Vinod Kumar Vavilapalli updated MAPREDUCE-3174:

    Priority: Blocker  (was: Minor)

Thomas, thanks for reporting.

This is more than a minor annoyance, we need to fix this before the release. Bumping its status
to a blocker.

Regarding possible solutions, we can have a Http-proxy at RM like Todd mentioned or we could
have a simple IFrame/JS in the AM web-UI which periodically checks the liveness of AM UI and
redirects to JobHistory when AM exits.

> A user can go to the application master UI to see the stats on the app, but as soon as
the app finishes that UI goes away and user is left with nothing.  A redirect to history server
or similar would be much better.
