 How to get JDBC driver
 =======================
 
+Direct Download
+--------------------------------
+
+You can directly download a JDBC driver jar file (``tajo-jdbc-x.y.z.jar``) from `Downloads
<http://tajo.apache.org/downloads.html>`_.

 From Binary Distribution

-Tajo binary distribution provides JDBC jar file and its dependent JAR files.

 Setting the CLASSPATH
 =======================
 
-In order to use the JDBC driver, you should set the jar files included in 
-``tajo-dist/target/tajo-x.y.z/share/jdbc-dist`` to your ``CLASSPATH``.
-In addition, you should add hadoop clsspath into your ``CLASSPATH``.
-So, ``CLASSPATH`` will be set as follows:
+In order to use the JDBC driver, you should add ``tajo-jdbc-x.y.z.jar`` in your ``CLASSPATH``.

-  You must add the locations which include Tajo config files (i.e., ``tajo-site.xml``) and

---------------------------------------------
-
-When retriving the final result, Tajo JDBC Driver tries to access HDFS data nodes.
-So, the network access between JDBC client and HDFS data nodes must be available.
-In many cases, a HDFS cluster is built in a private network which use private hostnames.
-So, the host names must be shared with the JDBC client side.
