Doesn't Spin the EMR instance if In private subnet.

[stormic-nomad-nishant]

Need to add the following service group inside ec2_attributes service_access_security_group = "${aws_security_group.emr_service_access.id}"

And the resource

resource "aws_security_group" "emr_service_access" {
  vpc_id                 = "${var.vpc_id}"
  revoke_rules_on_delete = true

  ingress {
   from_port   = 0
   to_port     = 65535
   protocol    = "tcp"
   #cidr_blocks = ["0.0.0.0/0"]
   self = true
  }

  tags {
    Name        = "sg${var.name}Service_Access"
    Project     = "${var.project}"
    Environment = "${var.environment}"
  }

}
