Arun C Murthy updated HADOOP-2726:
----------------------------------
Component/s: mapred
> Remove dead code block in JobInProgress.completedTask
> ------------------------------------------------------
>
> Key: HADOOP-2726
> URL: https://issues.apache.org/jira/browse/HADOOP-2726
> Project: Hadoop Core
> Issue Type: Improvement
> Components: mapred
> Affects Versions: 0.15.0
> Reporter: Arun C Murthy
> Fix For: 0.17.0
>
>
> Since the taskCommitThread ensures that one and only one task of a given TIP
> is marked as SUCCEEDED, we don't need the code block in
> JobInProgress.completedTask which checks if the TIP is complete and then just
> marks the task as complete:
> {noformat}
> // Sanity check: is the TIP already complete?
> if (tip.isComplete()) {
> // Mark this task as KILLED
> tip.alreadyCompletedTask(taskid);
> // Let the JobTracker cleanup this taskid if the job isn't running
> if (this.status.getRunState() != JobStatus.RUNNING) {
> jobtracker.markCompletedTaskAttempt(status.getTaskTracker(), taskid);
> }
> return false;
> }
> {noformat}
