No, have not resolved the issue. Still Wrote 105783245 bytes. If dbutils.fs.put(), which is:

put(file: String, contents: String, overwrite: boolean = false): boolean -> Writes the given String out to a file, encoded in UTF-8

Could instead be:

put(file: String, contents: String, overwrite: boolean = false, verbose: boolean = true): boolean -> Writes the given String out to a file, encoded in UTF-8, defaults message to stdout unless verbose=false

That would be great.
