>> You are trying to call an abstract method.  Please check the method DeferringRowReader.read


Do not know how to fix this issue.

Have seen in many tutorials around the net and those ones made the same calling I am currently doing


from pyspark_cassandra import CassandraSparkContext, Row

from pyspark import SparkContext, SparkConf

from pyspark.sql import SQLContext

conf = SparkConf().setAppName("test").setMaster("spark://").set("spark.cassandra.connection.host", "")

sc = CassandraSparkContext(conf=conf)

table = sc.cassandraTable("lebara_diameter_codes","nl_lebara_diameter_codes")

food_count = table.select("errorcode2001").groupBy("errorcode2001").count()



I am really new to this psark thing. Was able to configure it correctly nd now learning the API.
