Resolved! get a "Py4JJavaError: An error occurred while calling o5082.csv." when trying to save to csv file.

Hi, I'm trying to save a dataframe to csv with the code below:output.coalesce(1).write.mode('overwrite').option('header', 'true').csv(tmp_file_path) But it get "Py4JJavaError: An error occurred while calling o5082.csv." error. Any idea how to solve...

Resolved! How temporary is dbfs:/tmp/? Are files periodically deleted from there?
