Wrong variable name in test demo


 val receiverStream = RabbitMQUtils.createStream(ssc, Map(
      "hosts" -> hosts, 
      "queueName" -> queueName,
      "exchangeName" -> exchangeName,
      "exchangeType" -> exchangeType,
      "**_vHost_**" -> vHost,
      "userName" -> userName,
      "password" -> password
    ))


vhost is wrong
The correct variable name is virtualHost
