title: How Callback parameter works using WebHCat/Hive?
body: <p>I just followed the documentation in 
  <a href="https://cwiki.apache.org/confluence/display/Hive/WebHCat+Reference+Hive" rel="nofollow">WebHCat Reference Hive</a></p>
  
  <p>my goal is to call my spring controller once hive job status SUCCEEDED.</p>
  
  <pre><code>**here are my inputs :** 
  
  **url** : http://localhost:50111/templeton/v1/hive?user.name=hduser
  
  **Parameter:**
  callback : http://domain:port/project-name/mycall/$jobId
  </code></pre>
  
  <p>the $jobId is just a paramter it will be replaced to the actual jobId once processing is completed.</p>
  
  <pre><code>** here is my controller : ** 
  
  @RequestMapping(value = "/mycall/{jobId}", method = RequestMethod.GET)
      public void callBack( @PathVariable String jobId) throws IOException {
  LOGGER.debug("JobId : {}", jobId );
  }
  </code></pre>
