title: Hello World PipeLine with ShelCommandlActivity
body: <p>I'm trying to create a simple dataFlow pipeline with a single Activity of ShellCommandActivity type. I've attached the configuration of the activity and ec2 resource.</p>
  
  <p>When I execute this the Ec2Resource sits in the WAITING_ON_DEPENDENCIES state then after sometime changes to TIMEDOUT. The ShellCommandActivity is always in the CANCELED state. I see the instance launch and very quicky changes to the terminated stated.</p>
  
  <p>I've specified a s3 log file url, but that never gets updated.</p>
  
  <p>Can anyone give me any pointers? Also is there any guidance out there on debugging this?</p>
  
  <p>Thanks!!</p>
