+    <![CDATA[Provides access to configuration parameters.
+
+ <h4 id="Resources">Resources</h4>
+
+ <p>Configurations are specified by resources. A resource contains a set of
+ name/value pairs as XML data. Each resource is named by either a
+ <code>String</code> or by a {@link Path}. If named by a <code>String</code>,
+ then the classpath is examined for a file with that name.  If named by a
+ <code>Path</code>, then the local filesystem is examined directly, without
+ referring to the classpath.
+
+ <p>Unless explicitly turned off, Hadoop by default specifies two
+ resources, loaded in-order from the classpath: <ol>
+ <li><tt>
+ <a href="{@docRoot}/../hadoop-project-dist/hadoop-common/core-default.xml">
+ core-default.xml</a></tt>: Read-only defaults for hadoop.</li>
+ <li><tt>core-site.xml</tt>: Site-specific configuration for a given hadoop
+ installation.</li>
+ </ol>
+ Applications may add additional resources, which are loaded
+ subsequent to these resources in the order they are added.
+
+ <h4 id="FinalParams">Final Parameters</h4>
+
+ <p>Configuration parameters may be declared <i>final</i>.
+ Once a resource declares a value final, no subsequently-loaded
+ resource can alter that value.
+ For example, one might define a final parameter with:
+ <tt><pre>
+  &lt;property&gt;
+    &lt;name&gt;dfs.hosts.include&lt;/name&gt;
+    &lt;value&gt;/etc/hadoop/conf/hosts.include&lt;/value&gt;
+    <b>&lt;final&gt;true&lt;/final&gt;</b>
+  &lt;/property&gt;</pre></tt>
+
+ Administrators typically define parameters as final in
+ <tt>core-site.xml</tt> for values that user applications may not alter.
+
+ <h4 id="VariableExpansion">Variable Expansion</h4>
+
+ <p>Value strings are first processed for <i>variable expansion</i>. The
+ available properties are:<ol>
+ <li>Other properties defined in this Configuration; and, if a name is
+ undefined here,</li>
+ <li>Properties in {@link System#getProperties()}.</li>
+ </ol>
+
+ <p>For example, if a configuration resource contains the following property
+ definitions:
+ <tt><pre>
+  &lt;property&gt;
+    &lt;name&gt;basedir&lt;/name&gt;
+    &lt;value&gt;/user/${<i>user.name</i>}&lt;/value&gt;
+  &lt;/property&gt;
+
+  &lt;property&gt;
+    &lt;name&gt;tempdir&lt;/name&gt;
+    &lt;value&gt;${<i>basedir</i>}/tmp&lt;/value&gt;
+  &lt;/property&gt;</pre></tt>
+
+ When <tt>conf.get("tempdir")</tt> is called, then <tt>${<i>basedir</i>}</tt>
+ will be resolved to another property in this Configuration, while
+ <tt>${<i>user.name</i>}</tt> would then ordinarily be resolved to the value
+ of the System property with that name.
+ By default, warnings will be given to any deprecated configuration
+ parameters and these are suppressible by configuring
+ <tt>log4j.logger.org.apache.hadoop.conf.Configuration.deprecation</tt> in
+ log4j.properties file.]]>
