Thanks for the reply. Unfortunately this is the highest version available for
Cassandra connector.
One thing I don’t quite understand is that it worked perfectly under Spark
2.4.0. I thought support for Scala 2.11 only became deprecated starting spark
2.4.1, will be removed after spark 3.0

Scala version mismatched
Spark is shown at 2.12, the connector only has a 2.11 release

I run spark-submit I got following exceptions on Spark 2.4.2, it works fine
when running spark-submit under Spark 2.4.0 with exact the same command-line
call, any idea how do i fix this? Thanks a lot!
