@minahlee , could the class comment created by be used instead of @author tag in zeppelin sources?
or contributed by

@dlukyanov The reason I removed the author is not @author tag itself but because of ownership of the code. All code contributed to this repository is owned by Zeppelin community not by specific author.

I found one jira issue from Apache Taverna community which listed out discussion around it. Hope this help you to understand why we don't leave footprint in the code.
