Question

I am trying to run Spark through Spark connect on local machine.

The OS I am using is Ubunut using Spark 3.5.1 on JDK 17

Running Spark server through below command:

./start-connect-server.sh --packages org.apache.spark:spark-connect_2.13:3.5.1,com.microsoft.azure:spark-mssql-connector_2.12:1.2.0

It gives error in the logs as below

24/06/18 06:53:47 ERROR SparkContext: Error initializing SparkContext.
