Kinga Marton commented on YARN-9886:
------------------------------------
In the attached patch 001 I have addressed the following issues:
* changed the id pattern from {{userid=<userId>}} to {{u=<userId>}}
* added property for enabling this feature
* added a property for specifying the users who can do such operation
* added unit tests
I also wanted to add a small information to the documentation, but I didn't
found the proper place for it. I was searching for a part where the scheduler
common things are documented.

> There are situations when the real submitting user differs from the user what
> arrives to YARN. For example in case of a Hive application when Hive
> impersonation is turned off, the hive queries will run as Hive user and the
> mapping is done based on this username. Unfortunately in this case YARN
> doesn't have any information about the real user and there are cases when the
> customer may want to map this applications to the real submitting user's
> queue instead of the Hive one.
> For this cases if they would pass the username in the application tag we may
> read it and use that one during the queue mapping, if that user has rights to
> run on the real user's queue.
> [~sunilg] please correct me if I missed something.
