-------------------------------------

             Summary: unused vairaible
                 Key: ZEPPELIN-4448
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-4448
             Project: Zeppelin
          Issue Type: Improvement
          Components: zeppelin-server
            Reporter: Xiang Zhang


I see the method in ZeppelinServer.java

```

private static void setupNotebookServer(
 WebAppContext webapp, ZeppelinConfiguration conf, ServiceLocator 
serviceLocator) {
 String maxTextMessageSize = conf.getWebsocketMaxTextMessageSize();
 final ServletHolder servletHolder =
 new ServletHolder(serviceLocator.getService(NotebookServer.class));
 servletHolder.setInitParameter("maxTextMessageSize", maxTextMessageSize);

 final ServletContextHandler context = new 
ServletContextHandler(ServletContextHandler.SESSIONS);

 webapp.addServlet(servletHolder, "/ws/*");
}

```

The variable `context` is created but not used, is it intentional ?
