I am trying to submit a JAR file to Spark using /usr/local/spark# ./bin/spark-submit --class "DataframeExample" --master local[2] ~/new/hbfinance-module-1.0-SNAPSHOT.jar /. I'm using Apache Spark 1.5.0 and The console shows the application loads but then fails with this:

Try and open hbfinance-module-1.0-SNAPSHOT.jar in an archive explorer and see what class files it contains. By default, Maven is designed to only include your own class files in the built jar, not dependencies. When you run locally on your machine, the dependencies already exist on the classpath so you don't see any error, but when you sent it to Spark, the files are missing and an exception is thrown.
You can solve this in two ways:
Send all the jar-files for all your dependencies to Spark following these steps.
Build an "uber jar" of hbfinance-module using the Maven Shade Plugin following these steps.
