Subject [jira] Updated: (MAPREDUCE-1693) Process tree clean up of either a failed task or killed task tests.
Date Tue, 13 Apr 2010 18:05:01 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1693?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinay Kumar Thota updated MAPREDUCE-1693:
-----------------------------------------

    Description: 
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.

4. Submit a job which would spawn child processes and each of the child processes exceeds
the memory limits. Let the job complete . Check if all the child processes are killed, the
overall job should fail.

l)Submit a job which would spawn child processes and each of the child processes exceeds the
memory limits. Kill/fail the job while in progress. Check if all the child processes are killed.
