I changed to the call to include the args below and it worked. --num-executors 4 \ --executor-memory 512M \ --driver-memory 512M \

I changed the code to read from Hive instead and still got the same error. val sparkConf = new SparkConf().setAppName("test-spark").set("spark.eventLog.enabled", "true") val sc = new SparkContext(sparkConf) val sql = new HiveContext(sc) sql.sql("SELECT * FROM foodmart.customer").show() I added these args to the call but also no luck. --num-executors 4 \ --executor-memory 1G \ --driver-memory 1G \

I'm using spark to import data from a postgres database on my host machine into hdp sandbox. I get this error everytime. Here is the command call spark-submit \ --packages org.apache.spark:spark-streaming-kafka_2.10:1.6.0,com.databricks:spark-csv_2.10:1.5.0,com.databricks:spark-avro_2.10:2.0.1 \ --master yarn \ --deploy-mode client \ --jars ${L_ALL_JARS} \ --class ${L_CLASS} \ bdi.spark.jar ${HDM_CUSTOMER_KEY} yarn-client scala val sparkConf = new SparkConf().setAppName(args(2)) val sc = new SparkContext(sparkConf) val hive = new HiveContext(sc) val df = sql.read.format("jdbc").options(opts).load.cache df.show The error doesn't occur util I call an action on the dataframe show().
