Allen Wittenauer resolved HADOOP-6065.
--------------------------------------
Resolution: Incomplete
Closing this as stale.
> TestRunningTaskLimit doesnt work as expected
> --------------------------------------------
>
> Key: HADOOP-6065
> URL: https://issues.apache.org/jira/browse/HADOOP-6065
> Project: Hadoop Common
> Issue Type: Bug
> Components: test
> Reporter: Amar Kamat
>
> I see the following code in TestRunningTaskLimit
> {code}
> JobConf jobConf = createWaitJobConf(mr, "job1", 20, 20);
> jobConf.setRunningMapLimit(5);
> jobConf.setRunningReduceLimit(3);
>
> // Submit the job
> RunningJob rJob = (new JobClient(jobConf)).submitJob(jobConf);
>
> // Wait 20 seconds for it to start up
> UtilsForTests.waitFor(20000);
>
> // Check the number of running tasks
> JobTracker jobTracker = mr.getJobTrackerRunner().getJobTracker();
> JobInProgress jip = jobTracker.getJob(rJob.getID());
> assertEquals(5, jip.runningMaps());
> assertEquals(3, jip.runningReduces());
> {code}
> This check is timing based and might not work as expected. Instead we can run a job with > 5 maps (all waiting) and then wait for the job to reach a stable state and then test if exactly 5 maps were scheduled or not.
