Till Rohrmann commented on FLINK-13548:
---------------------------------------

I think we could add it to Flink. We should simply document that this feature 
only works with Hadoop >= 2.8. If there are API calls which are not available 
in earlier versions, then we could solve similar to 
https://github.com/apache/flink/blob/master/flink-yarn/src/main/java/org/apache/flink/yarn/RegisterApplicationMasterResponseReflector.java.

> Currently, Flink 1.9 does not support yarn priority submission. The default 
> priority of yarn submission jobs is based on YARN official doc.
> Based on this, we can provide a ConfigOption in YarnConfigOptions. The 
> priority value is non-negative, the bigger the number, the higher the 
> priority.  By default, we take -1. When the priority is negative, we use 
> default yarn queue priority.
