Wilfred Spiegelenburg commented on YARN-7769:
---------------------------------------------
OK, in that case we're ready to commit. +1 from my side.
[~snemeth]: I do think that we need to release note this as it is a difference
in behaviour. Do we also need to make sure that YARN-8951 works, or at least
does not throw a NPE and takes down the RM before we commit this?

> Currently the FairScheduler QueueManager automatically creates the default
> queue. However the default queue does not need to exist. We have two possible
> cases which we should handle:
> * Based on the placement rule "Default" the name for the default queue might
> not be default and it should be created with a different name
> * There might not be a "Default" placement rule at all which removes the need
> to create the queue.
> We should leave the creation of the default queue to the point in time that
> we can assess if it is needed or not.
