Task failures shouldn't result in Job failures
-----------------------------------------------
Key: MAPREDUCE-3473
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3473
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: tasktracker
Affects Versions: 0.23.0, 0.20.205.0
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.
