Subject Re: Spark error while trying to spark.read.json()

java.lang.AbstractMethodError almost always means that you have different
libraries on the classpath than at compilation time.  In this case I would
check to make sure you have the correct version of Scala (and only have one
version of scala) on the classpath.
