-<h2>Preliminary<a name="Preliminary"></a></h2>
-<p>Tajo's configuration is based on Hadoop's configuration system. Tajo
provides two config files:</p>
-<ul>
-<li>catalog-site.xml - configuration for the catalog server.</li>
-<li>tajo-site.xml - configuration for other tajo modules.</li></ul>
-<p>Each config consists of a pair of a name and a value. If you want to set
the config name <i>a.b.c</i> with the value <i>123</i>, add the following
element to an appropriate file.</p>
-<div>
-<pre> <property>
- <name>a.b.c</name>
- <value>123</value>
- </property></pre></div>
-<p>Tajo has a variety of internal configs. If you don't set some config
explicitly, the default config will be used for for that config. Tajo is
designed to use only a few of configs in usual cases. You may not be concerned
with the configuration.</p></div>
-<div class="section">
-<h2>Setting up catalog-site.xml<a name="Setting_up_catalog-site.xml"></a></h2>
-<p>If you want to customize the catalog service, copy $<a
name="TAJO_HOME">TAJO_HOME</a>/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.</p>
-<ul>
-<li><b>catalog.master.addr</b>
-<p>If you want to launch a catalog server separately, specify this address.
This config has a form of <i>hostname:port</i>. Its default value is
<i>localhost:9002</i>.</p></li>
-<li><b>org.apache.tajo.catalog.store.class</b>
-<p>If you want to change the persistent storage of the catalog server, specify
the class name. Its default value is <i>tajo.catalog.store.DBStore</i>. In the
current version, Tajo provides two persistent storage classes as follows:</p>
-<ul>
-<li>tajo.catalog.store.DBStore - this storage class uses Apache Derby.</li>
-<li>tajo.catalog.store.MemStore - this is the in-memory storage. It is only
used in unit tests to shorten the duration of unit
tests.</li></ul></li></ul></div>
-<div class="section">
-<h2>Setting up tajo-site.xml<a name="Setting_up_tajo-site.xml"></a></h2>
-<p>Copy $<a name="TAJO_HOME">TAJO_HOME</a>/conf/tajo-site.xml.templete to
tajo-site.xml. Then, add the following configs to your tajo-site.xml. <b>The
following two configs must be set to launch a tajo cluster.</b></p>
-<div>
-<pre> <property>
- <name>org.apache.tajo.rootdir</name>
- <value>hdfs://hostname:port/tajo</value>
- </property>
-
- <property>
- <name>org.apache.tajo.cluster.distributed</name>
- <value>true</value>
- </property></pre></div>
-<ul>
-<li><b>org.apache.tajo.rootdir</b>
-<p>Specify the root directory of tajo. This parameter should be a url form
(e.g., <i>hdfs://namenode_hostname:port/path</i>). You can also use
<i>file://</i> scheme.</p></li>
-<li><b>org.apache.tajo.cluster.distributed</b>
-<p>It is a flag used internally. It must be true.</p></li></ul>
-<p>The followings are other parameters. DO NOT modify the following configs
unless you are an expert of Tajo.</p>
