Hemanth Yamijala commented on HADOOP-4731:
------------------------------------------
Possibly there is no test case that completes a job without actually running
it, which is why this issue was never found. So, I would recommend introducing
a test that kills a queued job, and makes sure it is not there in the list.
> Job is not removed from the waiting jobs queue upon completion.

> Key: HADOOP-4731
> URL: https://issues.apache.org/jira/browse/HADOOP-4731
> Project: Hadoop Core
> Issue Type: Bug
> Components: contrib/capacity-sched
> Affects Versions: 0.19.0
> Reporter: Hemanth Yamijala
> Assignee: Amar Kamat
>
> When a job completes, the {{JobQueueManager}} removes this job from it's
> internal structures, which is a queue of the running jobs and waiting jobs.
> While the removal from the running jobs happens correctly, the removal from
> the waiting jobs does not happen, if the job is still in the PREP state. This
> was found while implementing HADOOP-4035, as described [by Vinod
> here|https://issues.apache.org/jira/browse/HADOOP-4035?focusedCommentId=12650879#action_12650879].
> The change was introduced in HADOOP-4471, which I should have caught in the
> review. Sorry about that !
