Subject [jira] [Updated] (MAPREDUCE-3032) JobHistory doesn't have error information from failed tasks
Date Tue, 11 Oct 2011 15:39:12 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3032?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Vinod Kumar Vavilapalli updated MAPREDUCE-3032:

    Status: Open  (was: Patch Available)

Can you debug why the diagnostics from the reportedStatus is empty? We need to make sure the
remote-diagnostics are not getting lost. Otherwise, we will only see the diagnostics produce
inside the AM.

Also, what is the test that you used and what is the error message that you saw?

In any case, there is one more occurrence of usage of the diagnostics-info from the 'reportedStatus'
in TaskAttemptImpl.getReport(), we should fix that.

Adding a test will greatly help this. You can look at TestMRApp|TestFail|TestKill for inspiration.
