Configurations are specified by resources. A resource contains a set of + name/value pairs as XML data. Each resource is named by either a + String or by a {@link Path}. If named by a String, + then the classpath is examined for a file with that name. If named by a + Path, then the local filesystem is examined directly, without + referring to the classpath. + +

Unless explicitly turned off, Hadoop by default specifies two + resources, loaded in-order from the classpath:

core-default.xml +: Read-only defaults for hadoop.
core-site.xml: Site-specific configuration for a given hadoop + installation.

+ Applications may add additional resources, which are loaded + subsequent to these resources in the order they are added. + +

Final Parameters

+ +

Configuration parameters may be declared final. + Once a resource declares a value final, no subsequently-loaded + resource can alter that value. + For example, one might define a final parameter with: +

+  <property>
+    <name>dfs.client.buffer.dir</name>
+    <value>/tmp/hadoop/dfs/client</value>
+    <final>true</final>
+  </property>

+ + Administrators typically define parameters as final in + core-site.xml for values that user applications may not alter. + +

Variable Expansion

+ +

Value strings are first processed for variable expansion. The + available properties are:

Other properties defined in this Configuration; and, if a name is + undefined here,
Properties in {@link System#getProperties()}.

+ +

For example, if a configuration resource contains the following property + definitions: +

+  <property>
+    <name>basedir</name>
+    <value>/user/${user.name}</value>
+  </property>
+  
+  <property>
+    <name>tempdir</name>
+    <value>${basedir}/tmp</value>
+  </property>

+ + When conf.get("tempdir") is called, then ${basedir} + will be resolved to another property in this Configuration, while + ${user.name} would then ordinarily be resolved to the value + of the System property with that name.]]> + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + BufferedFSInputStream + with the specified buffer size, + and saves its argument, the input stream + in, for later use.
