> Fair scheduler FIFO scheduling within a queue only allows 1 app at a time

> Key: YARN-336
> URL: https://issues.apache.org/jira/browse/YARN-336
> Project: Hadoop YARN
> Issue Type: Bug
> Components: scheduler
> Affects Versions: 2.0.2-alpha
> Reporter: Sandy Ryza
> Assignee: Sandy Ryza
> Attachments: YARN-336.patch

>
> The fair scheduler allows apps to be scheduled in FIFO fashion within a
> queue. Currently, when this setting is turned on, the scheduler only allows
> one app to run at a time. While apps submitted earlier should get first
> priority for allocations, when there is space remaining, other apps should
> have a change to get at them.
