I have pyspark code deployed on azure databricks, which basically reads and writes data to and from cosmosDB. In previous months, I used: DataBricks runtime Version: 6.4(Extended Support) with Scala 2.11 and Spark 2.45 Azure-cosmosdb-spark connector: azure-cosmosdb-spark_2.4.0_2.11-3.7.0-uber.jar Program runs fine with out any errors.
But, when I upgraded my runtime version to: DataBricks runtime Version: 10.4 LTS with Scala 2.12 and Spark 3.2.1 Azure-cosmosdb-spark connector: azure-cosmos-spark_3-2_2-12-4.10.0.jar
It throws me a error saying:

I have tried all the solutions available on internet. I know it comes when I am using 2.11 libraries on 2.12 project, but i am using 2.12 project and 2.12 spark connector itself. Yet i get the error.
Please let me know if any one is using the same environment. I use Databricks on Azure. Looking for a solution.
Any answers related to Databricks are really appreciated.
