title: Spark REST Api with spark 2.1
body: <p>We are trying to migrate from spark 1.6 to spark 2.1.
  I have tried configuring spark master and worker locally, and found that spark REST api is not same as it is earlier.</p>
  
  <p>With spark 1.6 when i started master, i used to get all the applications response using following url</p>
  
  <p><a href="http://localhost:8080/api/v1/applications" rel="nofollow noreferrer">http://localhost:8080/api/v1/applications</a></p>
  
  <p>Now, with spark 2.1, i tried the same, but it is not as expected.</p>
  
  <p><a href="http://localhost:8080/api/v1/applications" rel="nofollow noreferrer">http://localhost:8080/api/v1/applications</a> is just showing the web ui</p>
  
  <p>Am i missing any configurations.?</p>
