Problems with set-up enrichment/ emretlrunner for first time


Hi all,

We are trying to set-up snowplow for the first time, but are getting stuck at the enrichment step. The process we followed is:

  1. We set-up a cloudfront collecter, we created a bucket and installed a tracking pixel. We created a bucket for the logs and tested this and it worked.
  2. We installed a javascript pageview tracker (through GTM).
  3. We installed the EMLetlrunner. And create a file with the following lay-out:
  4. Our bucket layout in S3 looks as follows:
  • moongro (containing pixel)
  • moongrologfiles (containing logs)
  1. The code of our YAML config file (not sure how to put it in one of those grey blocks):
    access_key_id: XXX
    secret_access_key: XX
    region: eu-west-1
    assets: s3://snowplow-hosted-assets # DO NOT CHANGE unless you are hosting the jarfiles etc yourself in your own bucket
    jsonpath_assets: # If you have defined your own JSON Schemas, add the s3:// path to your own JSON Path files in your own bucket here
    log: s3://moongrologfiles/logs/
    in: # This is a YAML array of one or more in buckets - you MUST use hyphens before each entry in the array, as below
    - s3://moongrologfiles # e.g. s3://my-old-collector-bucket
    processing: s3://
    archive: s3:// # e.g. s3://my-archive-bucket/raw
    good: s3:// # e.g. s3://my-out-bucket/enriched/good
    bad: s3:// # e.g. s3://my-out-bucket/enriched/bad
    errors: # Leave blank unless :continue_on_unexpected_error: set to true below
    archive: s3:// # Where to archive enriched events to, e.g. s3://my-archive-bucket/enriched
    good: s3:// # e.g. s3://my-out-bucket/shredded/good
    bad: s3:// # e.g. s3://my-out-bucket/shredded/bad
    errors: # Leave blank unless :continue_on_unexpected_error: set to true below
    archive: s3:// # Where to archive shredded events to, e.g. s3://my-archive-bucket/shredded

  2. When in the terminal I run this:
    Compleet/snowplow-emr-etl-runner -c config/config.yml -r config/iglu_resolver.json

I get this message:

unsupported Java version “10”, defaulting to 1.7

Not sure what I am doing wrong, but all folders are still empty after running this. What am I doing wrong? Would greatly appreciate help. We were following the guide: but must’ve made a mistake somewhere.

Thanks in advance!



Make sure you’re running under Java 7 or 8 rather than 10.

You’ll also want to use tsv/ for the format parameter rather than cloudfront.


Thanks! That worked. Now I am getting the following error/ notification:
Configuration file ‘config/config.yml’ does not exist, or is not a file
Do you know what causes this? I have the configuration file saved as ‘config.yml’ in the config folder.

Have a nice day.


Already figured it out, it was a mistake in the command line.
