@felixcheung, I'm trying to fix the tests but I can't even run `npm run
test` in `zeppelin-web` because the file `webpack.config.js` made for version
`webpack 1` but the current version `4`.
They are not compatible between.
In addition, I counted at least 33 broken tests.
And i'm not strong in the frontend.---
