Wilfred Spiegelenburg commented on YARN-7769:
---------------------------------------------
Code change looks good. This does however also impact the
[documentation|https://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/FairScheduler.html]:
* {{By default, all users share a single queue, named “default”.}}
* {{user-as-default-queue}} says it falls back to the default queue
* {{allow-undeclared-pools}} is another point that mentions the default queue
The last impact is on the default placement rule. Not sure if that is just a
documentation change or a needs more.
> FS QueueManager should not create default queue at init

> 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.
