Subject [jira] Commented: (HADOOP-4615) Job submitted to an invalid queue still remains with the jobtracker
Date Mon, 10 Nov 2008 07:08:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12646185#action_12646185

Amar Kamat commented on HADOOP-4615:
------------------------------------

Hemanth, I am looking at this issue from the {{JobTracker}}'s point of view. This is what
is done today
- add job to {{JobTrackers's}} _jobs_ structure
- invoke {{jobAdded()}} for all the listeners

The problem is that the jobtracker informs the listener after adding the job to its _jobs_
structure. If one of the {{jobAdded()}} calls fails (invalid queue etc), we should remove
the job from the jobtracker and invoke {{jobRemoved()}} for each listener.

> If a job is submitted to an invalid queue, {{JobQueuesManager}} ignores it but {{Jobtracker}}
still considers the job as waiting.
