             Summary: When we submit spark core tasks frequently, the submitted nodes will have a lot of resource pressure
                 Key: SPARK-34406
                 URL: https://issues.apache.org/jira/browse/SPARK-34406
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.0.1
            Reporter: hao


When we submit spark core tasks frequently, the submitted node will have a lot of resource pressure, because spark will create a process instead of a thread for each submitted task. In fact, there is a lot of resource consumption. When the QPS of the submitted task is very high, the submission will fail due to insufficient resources. I would like to ask how to optimize the amount of resources consumed by spark core submission
