@Lallagreta You should be able to define the filename, or change the filename to what you want. That said the filename doesnt dictate the type, so you can have parquet saved as .txt. One recommendation I have is to use parquet command line tools during the testing of your use case. This is the best way to validate that files are looking right, have the right schema, and right results. https://pypi.org/project/parquet-tools/ I apologize i do not have any exact samples, but from my recall of a year ago, you should be able to get simple commands to check schema of a file, and another command to show the data results. You may have to copy your hdfs file to local file system to inspect them from command line.
