Doesn't even run...
I would like to run BasicLoadJson.java, but this does not work. I cloned the repo, maven clean build it and tried to run it, but I get the error
Error: A JNI error has occurred, please check your installation and try again

Why is that? What can I do?
Have you tried the directions in the readme? "./sbt/sbt assembly OR mvn package cd $SPARK_HOME; ./bin/spark-submit --class com.oreilly.learningsparkexamples.[lang].[example] ../learning-spark-examples/target/scala-2.10/learning-spark-examples-assembly-0.0.1.jar"
