Subru Krishnan commented on YARN-5203:
--------------------------------------
[~sunilg], thanks for taking a look and bringing up the important point on
compatibility.
IIUC unfortunately we cannot continue to have the raw RRs as JAXB will not be
able to unmarshal directly to {{AppInfo}} object. Today it works because
existing clients like UI deserialize directly to _String_ which should continue
to work even if we use JAXB object for RRs.
[~ellenfkh], can you kindly do a quick validation as you have a setup where you
already have been testing extensively. Thanks!

>
> The ResourceManager Cluster Applications REST API returns {{ResourceRequest}}
> as String rather than a JAXB object. This prevents downstream tools like
> Federation Router (YARN-3659) that depend on the REST API to unmarshall the
> {{AppInfo}}. This JIRA proposes updating {{AppInfo}} to return a JAXB version
> of the {{ResourceRequest}}.
