Subject [jira] [Updated] (MAPREDUCE-2460) TestFairSchedulerSystem failing on Hudson
Date Fri, 29 Apr 2011 02:43:03 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2460?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Todd Lipcon updated MAPREDUCE-2460:
-----------------------------------

    Attachment: mr-2460.txt

The issue seems to be that, when the job is retired, TaskGraphServlet no longer has any output.
So, we have a race where the job might get retired just before we fetch this servlet.

This patch catches the assertion error, and, if it sees that the job was retired, swallows
it.

I looped this on a Hudson box for several minutes and it passed reliably after this fix.
