Todd Lipcon commented on MAPREDUCE-2960:
----------------------------------------
This looks like it failed because of a failed disk on the *JT* rather than the
TT:
...
at org.apache.hadoop.fs.FileSystem.copyToLocalFile(FileSystem.java:1203)
at org.apache.hadoop.mapred.JobInProgress.<init>(JobInProgress.java:415)
...
are you running the JT on a machine that has bad disks simulated?
> A single TT disk failure can cause the job to fail

> Key: MAPREDUCE-2960
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2960
> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Components: tasktracker
> Affects Versions: 0.20.204.0
> Reporter: Eli Collins
>
> TaskInProgress#kill in the JT fails because TaskStatus#setFinishTimes fails
> because no start time was set. There's no start time because TaskTracker#run
> (DefaultTaskController#initializeJob) failed before it was set. The fix is to
> have TT#launchTask set the start time before it starts the task runner, this
> way there's a valid start time even if TT#run fails.
