Hi @Silver137. I think that the problem is a scala version compatibility issue. Unfortunately neither spark nor scala are usually compatible across versions. The version that ships in the big hadoop jar (elasticsearch-hadoop-8.2.2.jar) is for spark 2 / scala 2.11. Since you are using scala 2.13 and spark 3.3, you want to use the elasticsearch-spark-30_2.13 artifact (Maven Central Repository Search). You can read a little more about this at Issue Using the Connector from PySpark in 7.17.3 - #3 by Keith_Massey.
