title: Where does Hadoop store the logs of YARN applications?
body: <p>I run the basic example of Hortonworks' <a href="https://github.com/hortonworks/simple-yarn-app" rel="noreferrer">yarn application example</a>. The application fails and I want to read the logs to figure out why. But I can't find any files at the expected location (<code>/HADOOP_INSTALL_FOLDER/logs</code>) where the logs of my mapreduce jobs are stored.</p>
  
  <p>Does anybody know where yarn stores the non-mapreduce log files? Do I have to configure a special directory in the xml files?</p>
