Subject [jira] [Updated] (MAPREDUCE-2217) The expire launching task should cover the UNASSIGNED task
Date Wed, 02 Jan 2013 19:56:14 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2217?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Karthik Kambatla updated MAPREDUCE-2217:

    Attachment: expose-bug-mr-2217.patch

Sorry for the delay, just got around to this.

Uploading a patch that exposes the bug on clusters with some hosts with a 1 in their hostname.
Running a sample pi job with 4 nodes with common prefix followed by 01-04, results in the
job hanging at 75% map progress.

> The ExpireLaunchingTask thread kills the task that are scheduled but not responded.
> Currently if a task is scheduled on tasktracker and for some reason tasktracker cannot
put it to RUNNING.
