It should not block the 0.13 release. Possibly once it has been identified and fixed we can put it into a 13.1 release. > 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 > Assignee: Arun C Murthy > Fix For: 0.14.0 > > Attachments: DataNode1.log, DataNode2.log, JobTracker.log, NameNode.log, TaskTracker1.log, TaskTracker2.log, TestDFSIO.log > > > All maps had been completed successfully.
