Review Comment:
Fixed this too
> Replace all occurences of queuePath with the new QueuePath class - followup

>
> Key: YARN-11041
> URL: https://issues.apache.org/jira/browse/YARN-11041
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: capacity scheduler
> Reporter: Tibor Kovács
> Assignee: Peter Szucs
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.4.0
>
>
> The QueuePath class was introduced in YARN-10897, however, its current
> adoption happened only for code changes after this JIRA. We need to adopt it
> retrospectively.
>
> A lot of changes are introduced via ticket YARN-10982. The replacing should
> be continued by touching the next comments:

> I think this could be also refactored in a follow-up jira so the string magic
> could probably be replaced with some more elegant solution. Though, I think
> this would be too much in this patch, hence I do suggest the follow-up jira.|

> Agreed, let's handle it in a followup!|

> There are many string operations in this class:
> E.g. * getQueuePrefix that works with the full queue path
> * getNodeLabelPrefix that also works with the full queue path|
> I suggest to create a static class, called "QueuePrefixes" or something like
> that and add some static methods there to convert the QueuePath object to
> those various queue prefix strings that are ultimately keys in the
> Configuration object.

> This seems hacky, just based on the constructor parameter names of QueuePath:
> parent, leaf.
> The AQC Template prefix is not the leaf, obviously.
> Could we somehow circumvent this?|
> |[~bteke] [https://github.com/apache/hadoop/pull/3660#discussion_r765126207]
> Maybe a factory method could be created, which returns a new QueuePath with
> the parent set as the original queuePath. I.e
> rootQueuePath.createChild(String childName) -> this could return a new
> QueuePath object with root.childName path, and rootQueuePath as parent.|
> |[~snemeth] [https://github.com/apache/hadoop/pull/3660#discussion_r765039033]
> Looking at this getQueues method, I realized almost all the callers are using
> some kind of string magic that should be addressed with this patch.
> For example, take a look at:
> org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.conf.MutableCSConfigurationProvider#addQueue
> I think getQueues should also receive the QueuePath object instead of
> Strings.|

> The object of the queue suggests a CSQueue object.|
