Xuan Gong commented on YARN-6109:
---------------------------------
Thanks for the comments. [~subru].
After carefully investigation, I still prefer to create a separate ticket to
make sure reservation system work for Stop/Delete/Convert queue scenarios. And
we should do:
* For Delete/Convert a queue, we will make sure the current queue is in the
stopped state which means we should stop the queue first. For the reservation
system/plan queue, we should check the current leaf queue (if it is a parent
queue, check its children) whether it has the future reservations or not. If it
does not, we could stop the queue. Otherwise, we would throw out exception and
ask the user to remove the reservation first.
* To submits a reservation creation request, we should always make sure the
current leaf queue is in RUNNING state. Otherwise, we would reject the request.
[~leftnoteasy] [~subru] If you are fine with the plan, i will create a separate
ticket.
