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
.
In order to make the UI running on Ember server (started by yarn start
)
work with independently running ResouceManager,
you need to enable CORS by setting hadoop.http.cross-origin.enabled
to true
and adding org.apache.hadoop.security.HttpCrossOriginFilterInitializer
to hadoop.http.filter.initializers
in core-site.xml of the ResourceManager.
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 v1.21.1
- Install Bower v1.8.8
- 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
Building with Maven
YARN-6278
added yarn-ui
profile to pom.xml leveraging
frontend-maven-plugin which
automatically installs Node.js and Yarn locally under target/webapp directory.
After building yarn-ui by mvn package -Pyarn-ui
, you can reuse
the locally installed Node.js and Yarn instead of manually installing them.
$ mvn package -Pyarn-ui
$ export PATH=$PWD/target/webapp/node:$PATH
$ export YARNJS=$PWD/target/webapp/node/yarn/dist/bin/yarn.js
$ cd src/main/webapp/
$ node $YARNJS install
$ node node_modules/.bin/bower install
$ node $YARNJS start
