Hey Zheng, I don't know that there's a command to reload the properties file, but you can use the "hadoop daemonlog" command to change an individual logger at runtime. e.g: t...@todd-laptop:~$ hadoop-0.20 daemonlog -getlevel localhost:50030 org.apache.hadoop Connecting to http://localhost:50030/logLevel?log=org.apache.hadoop Submitted Log Name: org.apache.hadoop Log Class: org.apache.commons.logging.impl.Log4JLogger Effective level: INFO -Todd On Tue, Oct 20, 2009 at 10:41 PM, Zheng Shao <zs...@facebook.com<mailto:zs...@facebook.com>> wrote: Hi, Is there a command for JobTracker to reload the log4j settings at runtime?
