title: Launch EMR and kill it after running one JOB (automatically)
body: <p>I want to run a job each day automatically on Spark EMR, but i need to optimize my budget and use EMR only when I need it.</p>
  
  <p>So, is there a way to run an EMR (AWS) just for one job, then kill all instances after the job is finished (each X day).</p>
