Subject [jira] [Commented] (MAPREDUCE-3687) If AM dies before it returns new tracking URL, proxy redirects to http://N/A/ and doesn't return error code
Date Wed, 29 Feb 2012 15:03:58 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3687?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13219264#comment-13219264

Robert Joseph Evans commented on MAPREDUCE-3687:
------------------------------------------------

The patch looks OK, and I am OK with having no tests, as that part of the proxy has no unit
tests.

> I tried to turn on Uber AM and put 9223372036854775807l (last char is an L) for maxbytes.
 This caused a
> NumberFormatException in the AM and killed it.
> When I try to go to the RM proxy, it redirects me to http://N/A/
> curl -i http://resource.manager.example.com:$port/proxy/application_1326504761991_0001/
> HTTP/1.1 302 Found
> Content-Type: text/plain; charset=utf-8
> Location: http://N/A/

> Server: Jetty(6.1.26)
> Since the AM has no tracker URL, I would expect the return code to be 400~ or 500~ and
return an error.
