Subject [jira] Created: (MAPREDUCE-1646) Task Killing tests
Date Tue, 30 Mar 2010 10:21:27 GMT
Task Killing tests
------------------

                 Key: MAPREDUCE-1646
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1646
             Project: Hadoop Map/Reduce
          Issue Type: Task
          Components: test
            Reporter: Vinay Kumar Thota


The following tasks covered in the test.

1. In a running job, kill a task and verify the job succeeds.

2. Setup a job with long running tasks that write some output to HDFS. When one of the tasks
is running, ensure that
the output/_temporary/_attempt-id directory is created. Kill the task. After the task is killed,
make sure that the
output/_temporary/_attempt-id directory is cleaned up.

3. Setup a job with long running tasks that write some output to HDFS. When one of the tasks
is running, ensure that
the output/_temporary/_attempt-id directory is created. Fail the task by simulating the map.
After the task is failed,
make sure that the output/_temporary/_attempt-id directory is cleaned up. The important difference
we are trying to
check is btw kill and fail, there would a subtle difference.
