tooptoop4 commented on issue #27697: [SPARK-27750][CORE] Standalone scheduler - ability to prioritize applications over drivers, many drivers act like Denial of Service URL: https://github.com/apache/spark/pull/27697#issuecomment-592780445 1. one app is going to be slower 2. what if 7 out of 200 job fails, whole app fails meaning poor resumability. 3. files arrive at different times, so can't wait for all to arrive and then do single app. This PR fixes clear bug, spark standalone gets itself stuck. if you don't like the number 200, think of submitting 6 apps in cluster mode on a 4 core cluster, spark gets full of drivers and no apps can ever run, spark stays stuck forever. With this fix, I can guarantee some cores for apps so spark never gets stuck with only drivers
