SLIDER-453 AM queue processing goes live before init complete
> AM queue processing goes live before init complete
> --------------------------------------------------

> Key: SLIDER-453
> URL: https://issues.apache.org/jira/browse/SLIDER-453
> Project: Slider
> Issue Type: Bug
> Components: appmaster
> Affects Versions: Slider 0.60
> Reporter: Steve Loughran
> Assignee: Steve Loughran
>
> The AM queue executor goes live before AM startup; if external events come in
> (e.g. container completion reports), they aren't handled right. This is a
> re-emergence of a sync-startup problem seen before on restarted containers,
> as container completion comes in before cluster state buildup complete.
> Despite the sync block around app state, the extended AM is vulnerable to the
> same race condition.
> Fix: don't start the queues until the last moment...the events will just get
> scheduled awaiting that moment
