Parquet format table redetected as CSV

Parquet format table redetected as CSV


I've been running into an issue where after creating a dataset which is stored in parquet, while using a pyspark recipe, the dataset is redected as csv, without a very different schema.

Here's the dataset before pressing redetect format:

Original datasetOriginal dataset

And after pressing redetect format, It goes from 18 to 75 columns:

And the new columns make no sense:

New columns that shouldn't exist.New columns that shouldn't exist.

And to confirm the generated parquet files:

Parquet files.Parquet files.


I've deleted and recreated the dataset multiple times, but I always get the same result.

I've also checked the pyspark recipe, but it generates the 18 supposed columns, not 75.

Any help would be appreciated, as I'm at a loss on what could be causing this issue.


Best regards,
