ReturnContractError Contract violation for return value


#1

Im having issues with running snowplow-emr-etl-runner:

Does config varies depending on emr version you install? In setup guide it did not mention which version to use.

Here’s the error log:

    ReturnContractError (Contract violation for return value:

@jox, yes, it does. The configuration file format changes as the pipeline evolve. What version of the pipeline and EmrEtlRunner are you using?


#3

@ihor appreciate your response, Currently Im using snowplow_emr_r89_plain_of_jars.zip
and I follow the config example in github repo. Is there any way I could know which config or version to use?


#4

@jox, the parsing of the config.yml is done with EmrEtlRunner. It determines if the configuration file is in the correct format. The sample for this version is here. The EmrEtlRunner required to run the pipeline for this version is here. The links I provided could be obtained from our Upgrade Guide.
