[jira] [Created] (SPARK-32267) Decrease parallelism of PySpark tests on Jenkins

Hyukjin Kwon created SPARK-32267:
------------------------------------

             Summary: Decrease parallelism of PySpark tests on Jenkins
                 Key: SPARK-32267
                 URL: https://issues.apache.org/jira/browse/SPARK-32267
             Project: Spark
          Issue Type: Improvement
          Components: Project Infra, PySpark
    Affects Versions: 3.0.0, 2.4.6, 3.1.0
            Reporter: Hyukjin Kwon
            Assignee: Hyukjin Kwon


PySpark tests became flaky apparently due to the machines being slow. The parallelism of PySpark increased at SPARK-26148 to speed up.

Maybe we should decrease it to make the test stability better. It will only increase around 10 minutes which is rather a small portion compared to 6 ~ 7 hours in total testing time.
