Subject [jira] Created: (HADOOP-644) should dump stacks before timing out task
Date Thu, 26 Oct 2006 17:33:19 GMT
should dump stacks before timing out task

                 Key: HADOOP-644
                 URL: http://issues.apache.org/jira/browse/HADOOP-644
             Project: Hadoop
          Issue Type: New Feature
          Components: mapred
            Reporter: Doug Cutting

When a task process times out and is killed it is often difficult to determine why.  If its
stack was dumped prior to killing it, then debugging would be vastly simplified.  Ideally
the stack dump would be available through the web ui, but even the log would be sufficient.
