Here you go: https://gist.github.com/daschl/c2528af17af727d0688f4366d2177498 .. I ran a local master and worker and then published the same app into it with spark-submit. Note that our connector in this case is provided via --jars

(./spark-submit --jars ~/code/couchbase-spark-connector/target/scala-2.12/spark-connector-assembly-3.2.0-SNAPSHOT.jar --conf "spark.executor.extraJavaOptions=-verbose:class" --master spark://machine.local:7077 ~/code/scala/spark3-examples/target/scala-2.12/spark3-examples_2.12-1.0.0-SNAPSHOT.jar)
