Hello, I hope this is not a silly question. (I couldn't find any chat room on spark project, so asking on mail)
It has been about a year since using spark in work, and try to make a contribution to this project. I'm currently looking at documents in more detail, and checking the issue in JIRA now. Is there some suggestion of reviewing the code? - Which code part will be good to start? - What will be more helpful for the project? Thanks.
