I run the basic example of Hortonworks' yarn application example. 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 (/HADOOP_INSTALL_FOLDER/logs) where the logs of my mapreduce jobs are stored.

Does anybody know where yarn stores the non-mapreduce log files? Do I have to configure a special directory in the xml files?

Log-aggregation has been implemented in YARN, because of which the log file locations will vary when compared with Hadoop 1.

You can get the logs of your application in two ways, WebUi and Command line access.
