Spark 1.2.1 standalone cluster mode spark-submit is not working

Question

I have 3 node spark cluster

node1 , node2 and node 3

I running below command on node 1 for deploying driver

/usr/local/spark-1.2.1-bin-hadoop2.4/b

Answer 1

Cluster mode is not supported in EC2 1.2 instances where it creates a standalone cluster. Hence you can try removing

--deploy-mode cluster --supervise 

Answer 2

after spending lot more time.i got the answer.i did below changes

1. remove entry of SPARK_LOCAL_IP and SPARK_MASTER_IP
2. add host name and private ip address of each other nodes in etc/hosts.
3. use --deploy-mode cluster --supervise

thats all and it works perfectly with fully HA components(Master,Slaves and Driver)

Thanks
