  === Separating Configuration from Installation ===
  In the example described above, the configuration files used by the Hadoop cluster all lie in the Hadoop installation. This can become cumbersome when upgrading to a new release since all custom config has to be re-created in the new installation. It is possible to separate the config from the install. To do so, select a 
- directory to house Hadoop configuration (let's say {{{/foo/bar/hadoop-config}}}. Copy the {{{hadoop-site.xml, slaves}}} and {{{hadoop-env.sh}}} files to this directory. You can either set the {{{HADOOP_CONF_DIR}}} environment variable to refer to this directory or pass it directly to the Hadoop scripts with the {{{--config}}} option.
+ directory to house Hadoop configuration (let's say {{{/foo/bar/hadoop-config}}}. Copy all conf files to this directory. You can either set the {{{HADOOP_CONF_DIR}}} environment variable to refer to this directory or pass it directly to the Hadoop scripts with the {{{--config}}} option.
  In this case, the cluster start and stop commands specified in the above two sub-sections become [[BR]] {{{% $HADOOP_INSTALL/hadoop/bin/start-all.sh --config /foo/bar/hadoop-config}}} and [[BR]] {{{% $HADOOP_INSTALL/hadoop/bin/stop-all.sh --config /foo/bar/hadoop-config}}}. [[BR]] Only the absolute path to the config directory should be passed to the scripts.
