Spark submit cluster mode - Amazon Web Services

I am getting an error in launching the standalone Spark driver in cluster mode. As per the documentation, it is noted that cluster mode is supported in the Spark 1.2.1 release. However, it is currently not working properly for me. Please help me in fixing the issue(s) that are preventing the proper functioning of Spark.

I have a 3 node cluster and I am using the below Command for launching the driver from master node. The driver gets launched at a slave node and gives below error.

Command:

spark-1.2.1-bin-hadoop2.4]# /usr/local/spark-1.2.1-bin-hadoop2.4/bin/spark-submit --class com.mashery.firststep.aggregator.FirstStepMessageProcessor --master spark://ec2-xx.xx.xx.compute-1.amazonaws.com:7077 --deploy-mode cluster --supervise file:///home/xyz/sparkstreaming-0.0.1-SNAPSHOT.jar /home/xyz/config.properties
