title: hadoop streaming: how to see application logs?
body: <p>I can see all hadoop logs on my <code>/usr/local/hadoop/logs</code> path  </p>
  
  <p>but where can I see application level logs? for example :  </p>
  
  <p>mapper.py  </p>
  
  <pre><code>import logging
  
  def main():
      logging.info("starting map task now")
      // -- do some task -- //
      print statement  
  </code></pre>
  
  <p>reducer.py  </p>
  
  <pre><code>import logging
  def main():
      for line in sys.stdin:
          logging.info("received input to reducer - " + line)  
          // -- do some task -- //
          print statement
  </code></pre>
  
  <p>Where I can see <code>logging.info</code> or related log statements of my application?<br>
  I am using <code>Python</code> and using <code>hadoop-streaming</code>  </p>
  
  <p>Thank you</p>
