Hi: I am working on spark structured streaming (2.2.1) with kafka and want 100 executors to be alive. I set spark.executor.instances to be 100. The process starts running with 100 executors but after some time only a few remain which causes backlog of events from kafka. I thought I saw a setting to keep the executors from being killed. However, I am not able to find that configuration in spark docs. If anyone knows that setting, please let me know. Thanks
