E.g. Hadoop jar my.jar -D <property>=<value>

Subject: Dynamic reconfiguration of hadoop metrics plugin
Date: Fri, Jan 4, 2013 6:02 AM
Is there a way to dynamically reconfigure Hadoop metric plugins - for
example: by making changes to hadoop-metrics2.properties under conf
directory or by any commands?
Thanks and Regards,
