I'm also seeing this error.   Strangely I am including the jar in the spark submit command:   /usr/bin/spark-submit --class com.mycompany.myproduct.spark.sparkhive.Hive2RddTest --master spark://mycluster:7077 --executor-memory 8G --jars hive-common-0.13.1-cdh5.3.1.jar sparkhive.jar "/home/stunos/hive.json" &   Is this insufficient to add this to the classpath?

Does this mean I probably have to build Spark?         ... View more
