Subject [jira] Commented: (HADOOP-3698) Implement access control for submitting jobs to queues in the JobTracker
Date Thu, 21 Aug 2008 09:00:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3698?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12624293#action_12624293
] 

Hemanth Yamijala commented on HADOOP-3698:
------------------------------------------

Just a minor comment here that while queues are considered part of the framework, they still
are related to the scheduler that is configured. For e.g. the default scheduler {{JobQueueTaskScheduler}}
does not support more than one queue. So, if someone configures two queue names, and leaves
the scheduler as the default one, that might not work as expected. Probably the documentation
of the queue names' configuration parameter should document that there is a relationship.
Thanks to Sreekanth for pointing this out.

> HADOOP-3445 implements multiple queues in the JobTracker as part of the new resource
manager for Hadoop (HADOOP-3421). There needs to be a mechanism to control who can submit
jobs to a specified queue. This JIRA is for tracking the requirements, approach and implementation
for the same.
