Description

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
