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

- It seems like you have some issues with the IDE configuration.
{noformat}
+      while (counter  < 240) {
+	 UtilsForTests.waitFor(1000);
+	 counter ++;
+      }
+      if (counter == 240 ) {
+	 throw new IOException();
+      }
+    }
{noformat}
and many places like this. Please fix.
- also, I've tried to run it and it failed (see attached log)

> 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.
