             Summary: Tez UI: First Tab not needed for few entries in DAG listings
                 Key: TEZ-3428
                 URL: https://issues.apache.org/jira/browse/TEZ-3428
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Sreenath Somarajapuram
            Assignee: Sreenath Somarajapuram


All DAGs get listed in a table in the Tez view (navigated through Hive View's Query Tab) which allows for pagination. But when there are few DAGs ( less than 5 e.g.), then the navigation buttons still show Tab "First" and Tab "1" which can be misleading.
It would be better to show only the page number when there is only one page of DAGs. The "First" tab could become enabled/visible when there are more entries into the table and the user navigates to subsequent pages.

Suggested by ritticheria.
