title: How to set spark.driver.memory for Spark/Zeppelin on EMR
body: <p>When using EMR (with Spark, Zeppelin), changing <code>spark.driver.memory</code> in Zeppelin Spark interpreter settings won't work.</p>
  
  <p>I wonder what is the best and quickest way to set Spark driver memory when using EMR web interface (not aws CLI) to create clusters?</p>
  
  <p>Is Bootstrap action could be a solution?
  If yes, can you please provide an example of how the bootstrap action file should look like?</p>
