Stream Transfomer failing on output Parquet wide row

I have Dockerized version of Snowplow Stream Transformer Kinesis running in EKS and as i am going to store the data in Azure Databricks thats why i’m trying to write it as wide row and parquet format. but i’m getting the following error

Pleae note that it works great with wide row json

org.apache.hadoop.fs.UnsupportedFileSystemException: No FileSystem for scheme "s3"

And here is the config.hocon


  "input": {
    "streamName": "{{.Values.config.streams.good}}"
  "output": {
    "path": "s3://{{}}/transformed/"
  "windowing": "1 minutes",
  "queue": {
    "type": "sqs""queueName": "{{.Values.config.sqs}}"
  "formats": {
    "transformationType": "widerow",
    "fileFormat": "parquet"

This was fixed by changing the path from s3://** to s3a://

Glad you got that resolved!

As an aside its always worth checking out the logic baked into the open-source modules first when debugging as we have hopefully handled most of those cases and they can then be used as a template for building your own implementations (
