Github user bzz commented on the pull request: https://github.com/apache/incubator-zeppelin/pull/796#issuecomment-206187328 @johnnyws thank you for explanation. I think there is value in this PR not to changing the default behaviour that users already have for the 'root', single-folder case. Although having notebooks with the same name is very confusing in my experience and better be avoided. Uniq note name per-folded as @felizbear suggests makes sense to me and can be added here or later in a separate PR either as validation or as some composite key of the map.
