So the problem happend before that. And it looks like it is not reflected in the log. This is not windows related, I am running all these things on a linux machine. I'll try to debug it later today since nobody else can reproduce it. > TaskTracker falls into an infinite loop. > ---------------------------------------- > > Key: HADOOP-1374 > URL: https://issues.apache.org/jira/browse/HADOOP-1374 > Project: Hadoop > Issue Type: Bug > Components: mapred > Affects Versions: 0.12.3 > Reporter: Konstantin Shvachko > Assigned To: Arun C Murthy > Priority: Blocker > Fix For: 0.13.0 > > Attachments: DataNode1.log, DataNode2.log, JobTracker.log, NameNode.log, TaskTracker1.log, TaskTracker2.log, TestDFSIO.log > > > All maps had been completed successfully.
