It may also be good to add a "global" default action config file to
action-conf/ that gets applied to all action types.

Nevermind, it looks like there's already a config-default.xml, though its
currently broken (OOZIE-1644).
> "oozie.launcher.mapred.job.queue.name" as global property for oozie
> -------------------------------------------------------------------

> Key: OOZIE-1673
> URL: https://issues.apache.org/jira/browse/OOZIE-1673
> Project: Oozie
> Issue Type: New Feature
> Affects Versions: 4.0.0
> Reporter: Ostap
> Assignee: Ostap
>
> Currently, if not queue or a custom queue is set for an action, the launcher
> job will use the same queue.
> This leads to a deadlock situation in small clusters where all slots are
> taken by launcher jobs that cannot progress because there are not slots avail.
> That could be prevented by setting
> oozie.launcher.mapred.job.queue.name=launcherqueue.
> The problem is that we cannot specify the queue name on Oozie server. Each
> Oozie workflow job has to define its launcher job queue name
> (oozie.launcher.mapred.queue.name). If user didn’t specify this parameter in
> oozie’s job property, the “default” queue would be used for Launcher job,
> resulting in potential deadlock situation.
> We need to add a feature to Oozie so that it can take “oozie.launcher.xxx”
> parameter from oozie-site.xml so that user’s oozie job property doesn’t have
> to specify this parameter.
