> Race condition in command-line kill for a task
> ----------------------------------------------
>
> Key: HADOOP-5473
> URL: https://issues.apache.org/jira/browse/HADOOP-5473
> Project: Hadoop Core
> Issue Type: Bug
> Components: mapred
> Reporter: Amareshwari Sriramadasu
> Assignee: Amareshwari Sriramadasu
> Fix For: 0.19.2
>
> Attachments: patch-5473-1.txt, patch-5473-2.txt
>
>
> The race condition occurs in following sequence of events:
> 1. User issues a command-line kill for a RUNNING map-task. JT stores the task
> in tasksToKill mapping.
> 2. TT reports the task status as SUCCEEDED.
> 3. JT creates a TaskCompletionEvent as SUCCEEDED. Also sends a killTaskAction.
> 4. Reducers fail fetching the map output.
> 5. finally, the task would fail with Fetch failures. After HADOOP-4759, the
> task is left as FAILED_UNCLEAN task, since the task is present in tasksToKill
> mapping.
