These parameters can be set either from the `conf/flink-conf.yaml` or when starting the YARN session, using `-D` parameters. + +- `yarn.application.priority`: A non-negative integer indicating the priority for submitting a Flink YARN application. It will only take effect if YARN priority scheduling setting is enabled. Larger integer corresponds with higher priority. If priority is negative or set to '-1'(default), Flink will unset yarn priority setting and use cluster default priority, see [YARN Capacity Scheduling Doc](https://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/CapacityScheduler.html) for more info. Review comment: Thanks for the discussion on the JIRA issue! I will modify the doc description to specify the current supported version of YARN. And since most of our current jobs are still running with flink 1.5 API with priority feature we add, so the API calls 'appContext.setPriority' should be available in later versions. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
