  == Setting up catalog-site.xml ==
  If you want to customize the catalog service, copy $TAJO_HOME/conf/catalog-site.xml.templete to catalog-site.xml. Then, add the following configs to catalog-site.xml. Note that the default configs are enough to launch Tajo cluster in most cases.
  
-  * catalog.master.addr - If you want to launch a catalog server separately, specify this address. This config has a form of hostname:port. Its default value is localhost:9002.
+  * tajo.catalog.master.addr - If you want to launch a catalog server separately, specify this address. This config has a form of hostname:port. Its default value is 0.0.0.0:9002.
   * tajo.catalog.store.class - If you want to change the persistent storage of the catalog server, specify the class name. Its default value is tajo.catalog.store.DBStore. In the current version, Tajo provides two persistent storage classes as follows:
  
    * tajo.catalog.store.DBStore - this storage class uses Apache Derby.
