Key: MAPREDUCE-1693
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1693
Project: Hadoop Map/Reduce
Issue Type: Task
Components: test
Reporter: Vinay Kumar Thota
Assignee: Vinay Kumar Thota
Attachments: taskchildskilling_1693.diff
The following scenarios covered in the test.
1. Run a job which spawns subshells in the tasks. Kill one of the task. All the
child process of the killed task must be killed.
2. Run a job which spawns subshells in tasks. Fail one of the task. All the
child process of the killed task must be killed along with the task after its
failure.
3. Check process tree cleanup on paritcular task-tracker when we use -kill-task
and -fail-task with both map and reduce.
