Can pyspark use --archives to upload self-defined module than --py-files?

[zenglong chen]

Hi,all,
     '--py-files' upload zip files and spark python will import module like
'./xxx.zip/module_a/a.py'.
So can i use '--archives a.zip#a' to upload zip file and spark worker
python will import like ''./a/module/xx“？
What is the difference between '--py-files' and '--archives a.zip#a' to
upload self-defined module?
Thanks for answer！
