[ 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.
