Launch EMR in a VPC using boto

[AMAL G JOSE]

Hi,

I want to launch an EMR in a custom VPC using boto.

I am able to launch EMR in the default VPC, but I haven't seen any option in boto api for specifying the VPC. 

 Can anyone help me regarding this.?

Regards,

I found the solution.

In the current versions of boto there is no direct option to specify the subnet for launching EMR.

So we can pass the subnet id as an argument to the api_params option in the run_jobflow method of EmrConnection.

Pass Instances.Ec2SubnetId parameter and the value of this parameter as subnet-xxx as a parameter dictionary to the api_params argument in the run_jobflow method.

It worked perfectly for me.

Thanks.

In case some find this post useful, here's the codes.

  api_params = {"Instances.Ec2SubnetId":subnet_id}

  #Launching the cluster

  cluster_id = conn.run_jobflow(

               name,

               ec2_keyname=AWS_EC2_KEY_NAME,

               steps=[],

               keep_alive=False,

               master_instance_type = instance_type,

               slave_instance_type = instance_type,

               num_instances=2,

               ami_version=ami_version,

               api_params=api_params)
