Tested and it works well.
Could you setup travis-ci for your fork and see if it passes the test?
Please take a look
[CI](http://zeppelin.apache.org/contribution/contributions.html#continuous-integration).
Broken CI just fixed in master branch. So after setting up CI, you'll need
to rebase this branch from master.
