[jira] [Created] (SPARK-32878) Avoid scheduling TaskSetManager which has no pending tasks

wuyi created SPARK-32878:
----------------------------

             Summary: Avoid scheduling TaskSetManager which has no pending tasks
                 Key: SPARK-32878
                 URL: https://issues.apache.org/jira/browse/SPARK-32878
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.1.0
            Reporter: wuyi


Spark always tries to schedule a TaskSetManager even if it has no pending tasks. We can skip them to avoid any potential overhead.
