Subject [jira] Updated: (HADOOP-557) task tracker cannot find mapoutput files
Date Thu, 28 Sep 2006 20:26:52 GMT
     [ http://issues.apache.org/jira/browse/HADOOP-557?page=all ]

Sameer Paranjpye updated HADOOP-557:
------------------------------------

    Component/s: mapred
    Description: 
I ran a large job on our cluster over the weekend. At some point, some map tasks were re-run
successfully. However, when trying to handle the reducers requests to fetch mapoutput files
of those map tasks, the http server complained file not found.

This happened multiple times on different machines for the same map task until the job tracker
aborted the job.
