Naganarasimha G R commented on YARN-3368:

Well came across an issue while installing as per the readme.md in ubuntu 
14.04, 64 bit took little alternate steps to get it running (but in other 
Ubuntu setup steps in Readme.md was sufficient)
* sudo apt-get update
* sudo apt-get install nodejs
* sudo apt-get install npm

test following commands,
node --help
npm  --help

If the output is not coming then we can follow below steps :
*    sudo apt-get remove npm
*    sudo apt-get remove nodejs
*    wget http://nodejs.org/dist/v0.12.0/node-v0.12.7-linux-x64.tar.gz
*    sudo tar -C /usr/local --strip-components 1 -xzf 

*        ls -l /usr/local/bin/node
*        ls -l /usr/local/bin/npm

* sudo npm install bower -g
* sudo npm install -g ember-cli
* cd <code path>/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-ui
* npm install && bower install
no changes in yarn-app.js as per the configuration default settings of 
"http://localhost:1337/localhost:8088"; should work
* sudo npm install -g corsproxy
* nohup corsproxy > corsproxy.log 2>&1 &
* ember serve
* visit "http://localhost:4200";

> The goal is to improve YARN UI for better usability.
> We may take advantage of some existing front-end frameworks to build a 
> fancier, easier-to-use UI. 
> The old UI continue to exist until  we feel it's ready to flip to the new UI.
> This serves as an umbrella jira to track the tasks. we can do this in a 
> branch.
