-----------------------------------
Hi, [~templedf]
I think we can split the queue into three types:
1. Normal queue(The queue we currently use).
2. Disabled queue(The attributes are exactly the same as you think).
3. Exclusive queue(Make all sibling queues disabled).
I think this can perfectly meet my requirements, What do you think?
> add ability in Fair Scheduler to configure whether disable a queue

> In a production environment, emergency situations (such as the need to
> calculate the important reports) as soon as possible we need to disable all
> other queues, only allows the *RM* 's resources assigned to emergency queue
> and other queue only at the end of the urgent tasks before allowing them to
> be scheduled properly.
> At present, our approach is to write a script, in the case of an emergency
> manual changes all other queues' *minResources *and *maxResources * to *0mb,
> 0vcores* and then rebase it.This is very troublesome and easy to make
> mistakes.
> So we need to add a configuration in the *FairScheduler* configuration to
> indicate whether the queue is disabled, and if it is disabled, then *RM *will
> not allocate resources to the queue.
> * The child queue will integrate this property of the parent queue.
> * If the child queue is configured with this property, the value of the child
> queue configuration overrides the attributes of the parent queue.
> * The default value of the root queue is *enabled*.
> This will satisfy our needs, and I think other users will encounter such a
> scenario.I think this is very applicable to everyone.
