Subject [jira] Commented: (MAPREDUCE-1646) Task Killing tests
Date Fri, 09 Apr 2010 03:35:51 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1646?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12855263#action_12855263

Konstantin Boudnik commented on MAPREDUCE-1646:
-----------------------------------------------

Ok, sounds good to me. Most probably the issue I'm seeing is caused by the lack of LZO codec.
If there's no other comments from anyone please commit it to the internal Y20 branch and I'll
commit it to the trunk as soon as HADOOP-6332 is ready.

> 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.
