| <![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}/../core-default.html">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> |
| <property> |
| <name>dfs.client.buffer.dir</name> |
| <value>/tmp/hadoop/dfs/client</value> |
| <b><final>true</final></b> |
| </property></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> |
| <property> |
| <name>basedir</name> |
| <value>/user/${<i>user.name</i>}</value> |
| </property> |
| |
| <property> |
| <name>tempdir</name> |
| <value>${<i>basedir</i>}/tmp</value> |
| </property></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.]]> |
