Hi MUA, can you please firstly validate this DBFS path by using %fs ls bash command to list out the objects in this path? Then, the error OSError: [Errno 7] Argument list too long occurs when the number of command line arguments or the total size of the command line arguments is larger than the system's limit. This is a system-level error, not specific to any particular programming language or application by Spark. If the arguments can't be reduced, consider storing these arguments in a file and modify your script or command to read from this file instead of taking arguments from the command line.
args = json.loads(json_file_path)
print(args)
