"flintrock configure" issue

[trefoilai]

Dear Nicholas,

I am trying to use flintrock to launch a spark cluster for data science.I am walking trough the following tutorial "https://alexioannides.com/2016/08/18/building-a-data-science-platform-for-rd-part-2-deploying-spark-on-aws-using-flintrock/ ". I installed flitrock using the "pip3 install flintrock".
I checked if flintrock is well installed using the commando's flintrock --help.This returned

Usage: flintrock [OPTIONS] COMMAND [ARGS]...

  Flintrock

  A command-line tool for launching Apache Spark clusters.

Options:
  --config TEXT     Path to a Flintrock configuration file.
  --provider [ec2]
  --version         Show the version and exit.
  --help            Show this message and exit.

Commands:
  add-slaves     Add slaves to an existing cluster.
  configure      Configure Flintrock's defaults.
  copy-file      Copy a local file up to a cluster.
  describe       Describe an existing cluster.
  destroy        Destroy a cluster.
  launch         Launch a new cluster.
  login          Login to the master of an existing cluster.
  remove-slaves  Remove slaves from an existing cluster.
  run-command    Run a shell command on a cluster.
  start          Start an existing, stopped cluster.
  stop           Stop an existing, running cluster.

Which may means that everything is installed as expected. Then I wanted to configure the cluster and I ran the commando " flintrock configure" . This is what this returned

I have no clue what does that means.

Could you please help me figure out what the problem is?

Best regards

It looks like Flintrock can't find an editor on your system configured to open YAML files.

You can get around this easily by manually opening /home/hzmarrou/.config/flintrock/config.yaml with your favorite editor. That's all flintrock configure does anyway, after it creates that file with a bunch of defaults.

I think one thing Flintrock can do better here is to automatically give the advice I've just given if it detects that launching the editor failed.
