Weird behavior when using multiple services

[l1x]

This does not work:

def connect(emr=true, ec2=false)
options = {:region => @config["aws_region"]}
  if ec2
    @ec2_interface  = RightAws::Ec2.new(
      @config["aws_access_key_id"],
      @config["aws_secret_key_id"],
      options
    )
  end
  if emr
    @emr_interface  = RightAws::EmrInterface.new(
      @config["aws_access_key_id"],
      @config["aws_secret_key_id"],
      options
    )
  end
end

This does:

def connect(emr=true, ec2=false)
options = {:region => @config["aws_region"]}
  if ec2
    @ec2_interface  = RightAws::Ec2.new(
      @config["aws_access_key_id"],
      @config["aws_secret_key_id"],
      options
    )
  end
  if emr
    @emr_interface  = RightAws::EmrInterface.new(
      @config["aws_access_key_id"],
      @config["aws_secret_key_id"],
      :region => @config["aws_region"]
    )
  end
end

The error:

E, [2012-11-21T18:10:19.793520 #43919] ERROR -- : us-west-2.us-west-2.ec2.amazonaws.com temporarily unavailable: (getaddrinfo: nodename nor servname provided, or not known)
