Overview

The NodeManager REST API’s allow the user to get status on the node and information about applications and containers running on that node.

Enabling CORS support

To enable cross-origin support (CORS) for the NM only(without enabling it for the RM), please set the following configuration parameters:

In core-site.xml, add org.apache.hadoop.security.HttpCrossOriginFilterInitializer to hadoop.http.filter.initializers. In yarn-site.xml, set yarn.nodemanager.webapp.cross-origin.enabled to true.
