>
> When YARN RM HTTP response is a 404, the response body is empty and this
> results in an empty responseMap, that later caused Ambari server to crash
> with NPE when it tries to read properties from the responseMap.
> This JIRA proposes to set property values as null when the responseMap is
> null (due to empty body passed back from the YARN web server side).
