title: Replace LogStash with Spark Streaming
body: <p>My requirement is to read log data from multiple machines. 
  LogStash - As far as i understand, LogStash agents to be installed on all the machines and LogStash can push data to Kafka as and when it arrives i.e. even if a new line is added to a file, LogStash reads only that not the entire file again.</p>
