:: Experimental :: Hello @vruusmann , First of all I'd like to say that I've checked the issue #13 but I don't think it's the same problem. Optionally you can specify "/path/to/spark" in the initmethod above; findspark.init("/path/to/spark") Solution 3 Solution #1. Returns the currently active SparkSession, otherwise the default one. A SparkSession can be used create DataFrame, register DataFrame as tables, execute SQL over tables, cache tables, and read parquet files. response = connection.send_command(command) I don't know why "Constructor org.jpmml.sparkml.PMMLBuilder" not exist. First, as in previous versions of Spark, the spark-shell created a SparkContext ( sc ), so in Spark 2.0, the spark-shell creates a SparkSession ( spark ).
