Value guarded in: Snowplow::EmrEtlRunner::Cli::load_config

Anders_Kitson · January 10, 2020, 2:04am

I am very new to snowplow and yaml configs so I assume I am making a minor mistake here hopefully.

I am using this zip of emr snowplow_emr_r102_afontova_gora.zip

I am following these instructions https://github.com/snowplow/snowplow/wiki/1-Installing-EmrEtlRunner
the one part I didn’t set up was the storage part because I didn’t know where to put the reshift.json or other ones depending on what i used.

Ok thanks ahead of time hopefully someone can help me with this.

When I run
./snowplow-emr-etl-runner run -c config.yml -r iglu_resolver.json

this is my yaml config so far

aws:

  # Credentials can be hardcoded or set in environment variables

  access_key_id: 'ggg'

  secret_access_key: 'g+g'

@Anders_Kitson, here’s the example of correct configuration file format for the EmrEtlRunner you are using, R102: https://github.com/snowplow/snowplow/blob/r102-afontova-gora/3-enrich/emr-etl-runner/config/config.yml.sample.

Specifically,

Your raw:in bucket is expected to be an array of buckets
The job_name has to be moved out of immediate emr scope into emr:jobflow

That is

raw:
    in:
    - s3://enrich-in

and

emr:
    ami_version: 5.9.0      # Don't change this
    . . .
    jobflow:
      job_name: Snowplow ETL # Give your job a name

Do note deferent EmrEtlRunner versions might have different config format.

Anders_Kitson · January 10, 2020, 11:31pm

Thank you I will give the new config a try and report back. @ihor How do I know how many buckets are needed for the array, or is it just two like the example?

Anders_Kitson · January 10, 2020, 11:43pm

Ok It seemed to work now it said
No logs to process: No Snowplow logs to process since last run
But there are logs in elastic beanstock collector, so not sure if it was working 100%, but you solved my error. SO thank you so much.

Anders_Kitson · January 10, 2020, 11:48pm

@ihor, I don’t see anything in my s3 buckets. Should I at this stage? should there be initial test data in them?

Anders_Kitson · January 10, 2020, 11:58pm

Is my environent ID my app_id in the config.yml just not sure why I get no logs

ihor · January 10, 2020, 11:58pm

@Anders_Kitson, just an example. There could be many sources of raw events. You might have more than one collector to feed the data to the pipeline from.

Have you set up any collector to catch the data you track? If so, you need to make sure the data the collector collects ends up in the “raw” bucket (unless you enrich data in real-time pipeline).

If you set up Clojure collector the logs (raw events) are rotated by AWS once an hour and are beyond your control.

Anders_Kitson · January 10, 2020, 11:59pm

oh so I need to in my collector output the data to the raw bucket is there setup instructions for doing that. “just an example” do you mean I should see example data?

I think this is what I missed

ihor · January 11, 2020, 12:04am

Yes, it is important to enable log rotation to S3.
