Eric Yang commented on YARN-6626:
---------------------------------
This can be done by specifying hadoop-yarn-service-api as dependency to
hadoop-yarn-ui project, this will automatically place
hadoop-yarn-service-api*.jar and dependencies into WEB-INF/lib of
hadoop-yarn-ui war file. In web.xml file, specify:
{code}
<web-app>
<display-name>YARN UI</display-name>
<servlet>
<servlet-name>REST_API</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>org.apache.hadoop.yarn.appcatalog.controller;org.apache.hadoop.yarn.service.webapp</param-value>
</init-param>
<init-param>
<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>REST_API</servlet-name>
<url-pattern>/ws/v2/*</url-pattern>
</servlet-mapping>
</web-app>

> Embed REST API service into RM
> ------------------------------
>
> Key: YARN-6626
> URL: https://issues.apache.org/jira/browse/YARN-6626
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Gour Saha
> Fix For: yarn-native-services
>
>
> As of now the deployment model of the Native Services REST API service is
> standalone. There are several cross-cutting solutions that can be inherited
> for free (kerberos, HA, ACLs, trusted proxy support, etc.) by the REST API
> service if it is embedded into the RM process. In fact we can expose the REST
> API via the same port as RM UI (8088 default). The URI path
> /services/v1/applications will distinguish the REST API calls from other RM
> APIs.
