-----------------------------------
Hi [~boswell] thanks for the contribution.
I just come to realize that the priority scheduling feature was only there in
[YARN 2.8.x and
up|https://hadoop.apache.org/docs/r2.8.5/hadoop-yarn/hadoop-yarn-site/CapacityScheduler.html#Setup_for_application_priority.].
Although we can build Flink with Hadoop 2.8.x + using [specific
commands|https://ci.apache.org/projects/flink/flink-docs-stable/flinkDev/building.html#hadoop-versions].
I was wondering if we should implement a feature that only works in one
version.
CC [~till.rohrmann] who might have better insight here.

> 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.
