Jupyter Bootstrap Hangs on AWS EMR

[michaeljfazio]

I've written the following CloudFormation script to bootrstrap an EMR cluster on AWS.

Everything spins up fine except for the Jupyter Notebook bootstrap which seems to hang. Running the script manually after connecting via SSH I see the script gets to this point:

Warning: 'conda-forge' already in 'channels' list, moving to the top
++ /root/conda//bin/conda env update -f /tmp/gw-base.yml
Collecting package metadata (repodata.json): done
Solving environment: |

Another minor observation is that the script does not seem to correctly download the notebook examples as it fails to resolve the bucket token.
