Alejandro Abdelnur commented on MAPREDUCE-3649:
-----------------------------------------------

Looking at the code in the JobNotifier class:

{code}
      URLConnection conn = urlToNotify.openConnection();
      conn.setConnectTimeout(5*1000);
      conn.setReadTimeout(5*1000);
      conn.setAllowUserInteraction(false);
      InputStream is = conn.getInputStream();
      conn.getContent();
      is.close();
{code}

Instead it should be


{code}

      HttpURLConnection conn = (HttpURLConnection) urlToNotify.openConnection();
      conn.setConnectTimeout(5*1000);
      conn.setReadTimeout(5*1000);
      conn.setAllowUserInteraction(false);
      if (conn.getResponseCode() != HttpURLConnection.HTTP_OK) {
        //LOG WARNING
      }
{code}
