------

* Packaging and deploying Hadoop in this branch
* In `hadoop-yarn-project/hadoop-yarn/hadoop-yarn-ui/src/main/webapp/app/config.js`, change `timelineWebUrl` and `rmWebUrl` to your YARN RM/Timeline server web address. 
* If you are running YARN RM in your localhost, you should update `localBaseUrl` to `localhost:1337/`, install `npm install -g corsproxy` and run `corsproxy` to avoid CORS errors. More details: `https://www.npmjs.com/package/corsproxy`.
