Thanks @SachinJanani for contribution.
Could you try setup CI and see it this PR passes the CI 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
https://travis-ci.org/SachinJanani/zeppelin/settings.
To trigger CI after setup, you will need ammend your last commit with
git commit --amend
git push your-remote HEAD --force
See
http://zeppelin.apache.org/contribution/contributions.html#continuous-integration.
