Credentials

You can setup default credentials for all AWS services via AWS.config:

AWS.config(
  :access_key_id => 'YOUR_ACCESS_KEY_ID',
  :secret_access_key => 'YOUR_SECRET_ACCESS_KEY')

Or you can set them directly on the EMR interface:

emr = AWS::EMR.new(
  :access_key_id => 'YOUR_ACCESS_KEY_ID',
  :secret_access_key => 'YOUR_SECRET_ACCESS_KEY')

Job Flows

The #job_flows method returns a collection you use to interact with your job flows.

# creating a job flow
job_flow = emr.job_flows.create(...)

# enumerating job flows
emr.job_flows.each do |job_flow|
  puts job_flow.id
end

See JobFlowCollection and JobFlow for more information on working with job flows.
