I had the same issue. I have used the wrong library spark-sql-kafka library version (2.2.0 instead of 2.3.0). My successful configuration is:

org.apache.spark spark-core_2.11 2.3.0 provided

org.apache.spark spark-sql_2.11 2.3.0

org.apache.spark spark-sql-kafka-0-10_2.11 2.3.0

org.apache.kafka kafka-clients 0.10.1.0

I hope it helps. I got inspired by this post
