case class SparkPythonRunner(pyPaths: String, otherArgs: Array[String] = Array()) extends Product with Serializable

Internal class - should not be used by user

background: We had to "override" Spark's PythonRunner because we failed on premature python process closing. In PythonRunner the python process exits immediately when finished to read the file, this caused us to Accumulators Exceptions when the driver tries to get accumulation data from the python gateway. Instead, like in Zeppelin, we create an "interactive" python process, feed it the python script and not closing the gateway.
