------------------------------

             Summary: Avoid distribute user jar from driver in yarn client mode
                 Key: SPARK-33147
                 URL: https://issues.apache.org/jira/browse/SPARK-33147
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.0.1
            Reporter: dzcxzl


{code:java}
spark-submit --master yarn --deploy-mode client --num-executors 100 big_jar.jar
{code}
When the number of applied executors is large and the jar size is large, the executor pulls the jar from the driver, and the driver network traffic is high, and a timeout may occur. The driver and the executor of the yarn cluster may not be in the same data center.

{code}
 

We can automatically add the user's jar to --jars, which can avoid this problem.
