mridulm edited a comment on issue #27583: [SPARK-29149][YARN] Update YARN cluster manager For Stage Level Scheduling URL: https://github.com/apache/spark/pull/27583#issuecomment-586784460 General question about priority, I did not find much here [1]. How is the value of priority interpreted ? Is it simply to "tag" requests ? Or are higher priority requests 'prioritized' over lower priority requests from an application (to a queue) ? How does it compare with [2] ? Will that be cleaner ?
