Till Rohrmann commented on FLINK-13694:

Ok, now I understand [~yanghua]. But then the issue should be to make the user 
under which the Yarn application is submitted configurable. How to achieve this 
goal would be the implementation plan and here one could indeed discuss whether 
to reuse the {{ContainerOverlay}} or not. I guess this mainly depends on how 
big of an effort it would be and what the future direction of the 
{{YarnClusterDescriptor}} is.

>                 URL: https://issues.apache.org/jira/browse/FLINK-13694
>             Project: Flink
>          Issue Type: Improvement
>          Components: Deployment / YARN
>            Reporter: vinoyang
>            Priority: Major
> There is an abstract layer beyond special deployment named 
> {{ContainerOverlay}}. 
> However, currently, only Flink on Mesos used this mechanism. Flink on YARN 
> still used some trivial configuration items in 
> {{AbstractYarnClusterDescriptor}}. IMO we need to use container overlay to 
> refactor Flink on YARN related implementation.
