title: Managing Database Credentials from AWS EMR Spot Intsance
body: <p>I regularly spin up/shut down EMR clusters to perform a variety of tasks.  Some of these tasks include connecting to a remote database and reading or writing data.  I need various connection parameters to connect to these databases (address, username, pw, etc).  </p>
  
  <p>I am looking for a secure way to get these database credentials onto the EMR cluster during bootstrapping to be used by automated jobs.  I have access to all other AWS services.</p>
