> 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.
