Thanks @sancyx for the contribution.
It looks good, but i'd like to see if it passes CI.
Could you try setup CI and trigger build?
Looks like travis-ci is not configured for your fork.
Please setup by swich on 'zeppelin' repository at
https://travis-ci.org/profile and travis-ci.
And then make sure 'Build branch updates' option is enabled in the settings
To trigger CI after setup, you will need ammend your last commit with
git commit --amend
git push your-remote HEAD --force
Build step 'Execute shell' marked build as failure
Putting comment on the pull request
Let me know if you need any help on CI.
