4.9. Reconfiguring Hadoop after Installation

The configuration of Hadoop is done during the install, the resulting configuration file is /etc/sysconfig/hadoop. To reconfigure Hadoop on a node, make appropriate attribute using the commands above and then run

# rocks sync host osg hadoop <hostname>

This will rewrite the file /etc/sysconfig/hadoop and then calls the Hadoop command /root/HadoopConfigurator

To view the contents of the /etc/sysconfig/hadoop before making changes, use rocks report host osg hadoop config <hostname>
