#master_public_dns_name ⇒ `String`

The DNS name of the master node. If the cluster is on a private subnet, this is the private DNS name. On a public subnet, this is the public DNS name.

Returns:

(String)

# File 'gems/aws-sdk-emr/lib/aws-sdk-emr/types.rb', line 4038

  include Aws::Structure
end

#normalized_instance_hours ⇒ `Integer`

An approximation of the cost of the cluster, represented in m1.small/hours. This value is increased one time for every hour that an m1.small instance runs. Larger instances are weighted more heavily, so an Amazon EC2 instance that is roughly four times more expensive would result in the normalized instance hours being increased incrementally four times. This result is only an approximation and does not reflect the actual billing rate.

Returns:

(Integer)
