    I am using Spark with as processing engine over cassandra. I have only one master and a worker node. I am executing following code in spark-shell : sc.stop import org.apache.spark.SparkContext import org.apache.spark.SparkConf import com.datastax.spark.connector._ val conf = new

println(rdd.map(_.getInt("value")).sum) I am getting following error: 14/08/25 18:47:17 WARN Utils: Set SPARK_LOCAL_IP if you need to bind to another address 14/08/25 18:49:39 INFO
