To start the SparkR CLI shell, we just need the --master parameter to connect to the desired cluster. Based on our use case, the connection parameters will change along with the packages being used for the connection.

If any of them are not enabled on the Cassandra side, those parameters need to be removed accordingly. An example format for connecting to a Cassandra node with authentication and SSL enabled is as follows:
# To Start SparkR shell with master or slave.# Remove authentication or ssl parameters based on cassandra side enabling$SPARK_HOME/bin/SparkR ...
