-----------------------------------------

             Summary: need to show application page even if system metrics publish is disabled.
                 Key: TEZ-2660
                 URL: https://issues.apache.org/jira/browse/TEZ-2660
             Project: Apache Tez
          Issue Type: Bug
          Components: UI
            Reporter: Prakash Ramachandran


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
