> This ticket is intended to fix two issues:
> 1. Based on the latest documentation, there are two important properties that
> are ignored if we have placement rules:
> ||Property||Explanation||
> |yarn.scheduler.fair.allow-undeclared-pools|If this is true, new queues can
> be created at application submission time, whether because they are specified
> as the application’s queue by the submitter or because they are placed there
> by the user-as-default-queue property. If this is false, any time an app
> would be placed in a queue that is not specified in the allocations file, it
> is placed in the “default” queue instead. Defaults to true. *If a queue
> placement policy is given in the allocations file, this property is ignored.*|
> |yarn.scheduler.fair.user-as-default-queue|Whether to use the username
> associated with the allocation as the default queue name, in the event that a
> queue name is not specified. If this is set to “false” or unset, all jobs
> have a shared default queue, named “default”. Defaults to true. *If a queue
> placement policy is given in the allocations file, this property is ignored.*|
> Right now these settings affects the conversion regardless of the placement
> rules.
> 2. A converted configuration throws this error:
