title: Zeppelin 0.7.1 does not highlight according to code syntax
body: <p>I just installed Zeppelin 0.7.1 through HDP and Ambari and the code highlights dont work anymore. Code runs normally but there is no highlights anymore for some reason. Any suggestions what components I should look at to fix this?</p>
  
  <p>Edit:</p>
  
  <p>I just noticed that this problem only applies for yarn-client mode. In local mode the highlighting works fine.</p>
