Hi @tmslara.a. Sorry for the slow response, but I think you are probably right about the versioning error. Es-hadoop/spark packaging is a bit confusing. The elasticsearch-hadoop-8.11.3.jar contains a default version of es-spark that is probably not appropriate for your setup. You want to use [elasticsearch-spark-30_2.13-8.11.3.jar](https://central.sonatype.com/artifact/org.elasticsearch/elasticsearch-spark-30_2.13/8.11.3) if you are running scala 2.13, or [elasticsearch-spark-30_2.12-8.11.3.jar](https://central.sonatype.com/artifact/org.elasticsearch/elasticsearch-spark-30_2.12/8.11.3) if you are running scala 2.12.
See Issue Using the Connector from PySpark in 7.17.3 - #3 by Keith_Massey for an old post about this.
