--------------------------------------------------------------
As a conclusion of an offline discussion with [~sunilg] we have agreed on the
following:
* We will keep the username in the tag, but I will change the pattern to
{{u=<userid>}}
* I will add a configuration to enable/disable the application placement using
the application tag. This way we can keep the backward compatibility and avoid
any undesired side effects.

> 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.
