URL: https://github.com/apache/kyuubi/pull/4381#issuecomment-1442871106

   > Moved `PySparkTests` from the module `kyuubi-spark-sql-engine` to 
`kyuubi-server` to ensure that the python progress loading library PYSPARK has 
the same version as the launched Spark engine.
   
   FYI:
   
   the signature of the method`pyspark.sql.SparkSession.sql()` is changed after 
https://github.com/apache/spark/pull/39971, there is a compatibility issue if 
the loaded pyspark library is version 3.4.0 but the launched spark engine is 
version 3.3.2.
