dzcxzl created SPARK-33147:
------------------------------
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.

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