The error message says Use 'org.elasticsearch.spark.sql' package instead but what exactly does that mean?

We provide native support for Spark SQL DataFrames and Datasets in ES-Hadoop. These often require some different logic to handle the serialization correctly. Please take a look at our documentation section about SparkSQL for the correct API calls.
