Answer 1

Message No suitable driver found for means, that proper jdbc driver cannot be found.

According to article to fix above error you need to place appropriate jdbc driver in share/java/kafka-connect-jdbc

To use the JDBC connector, you’ll need to make available the relevant JDBC driver for your source database. The connector ships with drivers for PostgreSQL and sqlite—for all others download the appropriate JAR and place it in share/java/kafka-connect-jdbc. You can find the relevant downloads here for MySQL, Oracle, SQL Server, DB2, and Teradata.

After copying jars, you need to restart Kafka Connect
