[jira] [Created] (MAPREDUCE-3174) app master UI goes away when app
finishes - not very user friendly
app master UI goes away when app finishes - not very user friendly
------------------------------------------------------------------
Key: MAPREDUCE-3174
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3174
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: mrv2
Affects Versions: 0.23.0
Reporter: Thomas Graves
Priority: Minor
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.

[jira] [Updated] (MAPREDUCE-3174) app master UI goes away when app

-----------------------------------------------
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.

------------------------------------------------
I am already putting in a proxy in the RM as part of MAPREDUCE-2858. It should fix most of this automatically. There is the case where the RM no longer knows about the application so it will not be able to forward it automatically to the history server.

I'm not sure this is a blocker - yes we can improve this, but doesn't block a release.

Todd Lipcon commented on MAPREDUCE-3174:
----------------------------------------
Seems like we can attack it in two parts. The first, easier, and more critical part, is to do the redirect when the RM still remembers the application. The harder one as you mention is when the RM has restarted or retired the app information. Let's attack the easy one for 0.23.0 and the harder one later?

+1 - I think the user should view the app master UI through an HTTP proxy running as part of the RM.
