Debug Spark program in Eclipse Data in AWS

hi All

       i am trying to run debug spark program in eclipse on Cloudera cluster on AWS EC2. i tried 

val conf = new SparkConf().setAppName("WordCount").setMaster("yarn-client")

val conf = new SparkConf().setAppName("WordCount").setMaster("local[3]")

       i find out i am facing an issue . the namenode in the AWS EC2 cluster return me the private IP in AWS.like 

172.31.26.79,172.31.26.80 etc.. which my local windows mechine not able to resolve . 

      Any idea how to handle all this ?

It's also possible to establish an ssl tunnel in order to connect to a remote debug session.  Take a look at the -L option for ssh, you will be able to open a local port and setup the remote port within the ssh command.  This will work for private IPs as long as you can connect to a server from a public IP that has access to the private network.  Note though that there can be extreme latency and still be difficult to debug in setups like this.

I know move the program inside the cluster network will help ~ but sometime you can't move the program into the cluster

Thank you for your reply . 

I solve the issue by create another node in the AWS EC2 as workspace through that node to connect to other AWS EC2 cluster .
