Subject [jira] Updated: (HADOOP-4445) Wrong number of running map/reduce tasks are displayed in queue information.
Date Fri, 05 Dec 2008 06:00:44 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-4445?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sreekanth Ramakrishnan updated HADOOP-4445:
-------------------------------------------

    Attachment: HADOOP-4445-1.patch

Attaching a patch fixing this issue:

The patch does the following:

1. in SchedulingInfo.toString() it does JobQueueManager.getRunningJobs(queue) and iterates
thro' running job list and keeps adding number of running tasks in the queue. We need not
worry about the jobs which are initialized but not scheduled as those jobs would have running
maps and reduces as zero.
2. Modified testSchedulingInfo() by assigning a map and reduce task to the tracker and check
the number of running tasks. Then finished the job and checked the same.  Then check for case
where running job fails.

I have moved the comment from within testSchedulingInfo() to outside. I have removed the FakeJobInProgress.fail()
and I am using taskTrackerManager.finalizeJob api instead as the latter raises events which
is required for cleaning up the running job queues.
