YARN UI

The YARN UI is an Ember based web-app that provides visualization of the applications running on the Apache Hadoop YARN framework.

Configurations

• You can point the UI to custom locations by setting the environment variables in src/main/webapp/config/configs.env

Development

All the following commands must be run inside src/main/webapp.

Prerequisites

You will need the following things properly installed on your computer.

• Install Yarn v0.21.3
• Install Bower v1.7.7
• Install all dependencies by running yarn install & bower install

Running UI

• yarn start
• Visit your app at http://localhost:4200.

Building

• yarn run build (production)
• Files would be stored in "dist/"

Adding new dependencies

Warning: Do not edit the package.json or bower.json files manually. This could make them out-of-sync with the respective lock or shrinkwrap files.

YARN UI has replaced NPM with Yarn package manager. And hence Yarn would be used to manage dependencies defined in package.json.

• Please use the Yarn and Bower command-line tools to add new dependencies. And the tool version must be same as those defined in Prerequisites section.
• Once any dependency is added:
  • If it's in package.json. Make sure that the respective, and only those changes are reflected in yarn.lock file.
  • If it's in bower.json. Make sure that the respective, and only those changes are reflected in bower-shrinkwrap.json file.
• Commands to add using CLI tools:
  • Yarn: yarn add [package-name]
  • Bower: bower install --save [package-name]

Adding new routes (pages), controllers, components etc.

• Use ember-cli blueprint generator - Ember CLI
