Wangda Tan commented on YARN-9879:
----------------------------------
Thanks [~shuzirra], I think adding a flag (suggestion from [~adam.antal]) will
prevent admin to change it accidentally, but it is hard to be understand
(thinking about a regular Hadoop user). And we need to maintain it in a long
run.
So instead, I would like to allow user to make changes but fail the application
submission with a clear message (like you cannot submit the application because
there're multiple queue with the name XYZ, you can make change to use the full
qualified queue name or remove/rename duplicated queues, etc.). If admin want
to regret and make changes back, they can easily do that.
