|
|
<p>To enable cross-origin support (CORS) for the NM only(without enabling it for the RM), please set the following configuration parameters:</p>
|
|
<p>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.</p></section><section>
