> 1. When stopping a running parent queue, error message thrown by API was not meaningful.
> For example: When tried to stop root queue, error message thrown was  {{Failed to re-init queues : The parent queue:root state is STOPPED, child queue:default state cannot be RUNNING.}}  
> It is evident that root queue update failed, but the message says {{queue:root state is STOPPED}}.
> 2. While tried to delete a running leaf queue, error message thrown by API was not meaningful.
> For example: Error message was {{Failed to re-init queues : root.default.prod is deleted from the new capacity scheduler configuration, but the queue is not yet in stopped state. Current State : RUNNING}}.
> Clearly deletion of queue root.default.prod failed with error, but the message says {{queues : root.default.prod is deleted from the new capacity scheduler configuration}}.
