Yes that should be fine. 

Does this require cors support in YARN RM? Does this degrade gracefully if the data cannot be read from RM or error out? Might be better to display some message saying that data could not be retrieved from RM/ATS but allow the UI to function?

> if system metrics publish is disabled the application page is not shown currently. This means the following does not work. 
> * history url from yarn ui will redirect to a page which will error
> * we do not show the url from tez-ui to yarn app page.
> This can be enhanced and fixed by using the data if its available through the yarn rest api. https://hadoop.apache.org/docs/r2.4.1/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html#Cluster_Applications_API
