Eric Yang commented on YARN-6626:
---------------------------------
[~jianhe] Resource Manager jetty server is setup to chain a series of
WebFilters together. Every web filter is extended from WebServices. This is
how YARN web application written to work. Resource.java was changed to return
cloned object instead of internal data structure to prevent the internal
structure to be modified by code outside of YARN jar file. This was flagged by
Findbugs. @XmlType annotation is for Jersey to validate the data structure
schema. Without, XmlType annotation, jersey will write exceptions in Resource
Manager server log file.
I will update the patch with default to false, and update QuickStart.md
tomorrow.

> 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.
