Hadoop: YARN-UI V2
=================
Prerequisites
-------------
If you run RM locally in your computer for test purpose, you need the following things properly installed.
- Install Node.js with NPM: https://nodejs.org/download
- After Node.js installed, install `corsproxy`: `npm install -g corsproxy`.
Configurations
-------------
*In yarn-site.xml*
*In `yarn-site.xml`*
| Configuration Property | Description |
|:---- |:---- |
| `yarn.resourcemanager.webapp.ui2.enable` | In the server side it indicates whether the new YARN-UI v2 is enabled or not. Defaults to `false`. |
| `yarn.resourcemanager.webapp.ui2.address` | Specify the address of ResourceManager and port which host YARN-UI v2, defaults to `localhost:8288`. |
| `yarn.webapp.ui2.enable` | *(Required)* In the server side it indicates whether the new YARN-UI v2 is enabled or not. Defaults to `false`. |
| `yarn.webapp.ui2.war-file-path` | *(Optional)* WAR file path for launching yarn UI2 web application. By default this is empty and YARN will lookup required war file from classpath |
*In $HADOOP_PREFIX/share/hadoop/yarn/webapps/rm/config/configs.env*
Please note that, If you run YARN daemons locally in your machine for test purpose,
you need the following configurations added to `yarn-site.xml` to enable cross
origin (CORS) support.
- Update timelineWebAddress and rmWebAddress to the actual addresses run resource manager and timeline server
- If you run RM locally in you computer just for test purpose, you need to keep `corsproxy` running. Otherwise, you need to set `localBaseAddress` to empty.
| Configuration Property | Value | Description |
|:---- |:---- |:---- |
| `yarn.timeline-service.http-cross-origin.enabled` | true | Enable CORS support for Timeline Server |
| `yarn.resourcemanager.webapp.cross-origin.enabled` | true | Enable CORS support for Resource Manager |
| `yarn.nodemanager.webapp.cross-origin.enabled` | true | Enable CORS support for Node Manager |
