Description

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.
