I am trying to use mysql jdbc driver mysql-connector-java-5.1.15.jar to set up the connection from Spark, I received the error message:

java.sql.SQLNonTransientConnectionException: CLIENT_PLUGIN_AUTH is required

I also tried a newer version: mysql-connector-java-8.0.15.jar, same error.

I also tried to use useSSL=false in the jdbc connection string, same error.



Can anyone help to get this sorted out? Thank you very much.
