> TEZ-3428.1.patch
> 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.
