Subject [jira] Commented: (MAPREDUCE-1646) Task Killing tests
Date Thu, 01 Apr 2010 20:12:28 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1646?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12852529#action_12852529

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

Well, looks like {noformat} did a bad job in the above snippet case. What I've meant is that
in say line 128 all indentation is done with whitespaces, but in line 129 and other 3 after
it the indentation is tabs + whitespace. Different IDEs might be configured differently about
the size of the tabs. I.e. for Hadoop style the size of tab is 2. Thus in some people editors
tabs will be looking differently which might lead to unnecessary reformatting of the code.

> 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.
