Hi, Depends on what kind of logging your looking for. Best guess is to look for the following files on your cluster: ./hadoop-env.sh ./yarn-site.xml ./log4j.properties ./mapred-site.xml
You can control the level of logging (info, warning) and the location through these files. If you have an administrator console, look into the "HDFS" , "Yarn" and "Mapreduce" section.

Date: Wed, 10 Jun 2015 18:26:37 -0400 Hello, I’m running Hadoop 2.6.0 and while the cluster runs I’ve not seen a log created/written in the expected place. What could cause this? Is it writing to another place? What is the default directory? Thank you, Caesar.
