It can, that's the point of this bug! > A single task tracker failure shouldn't result in Job failure > -------------------------------------------------------------- > > Key: MAPREDUCE-3473 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3473 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: tasktracker > Affects Versions: 0.20.205.0, 0.23.0 > Reporter: Eli Collins > > Currently some task failures may result in job failures. Eg a local TT disk failure seen in TaskLauncher#run, TaskRunner#run, MapTask#run is visible to and can hang the JobClient, causing the job to fail. Job execution should always be able to survive a task failure if there are sufficient resources. -- This message is automatically generated by JIRA.
