All Implemented Interfaces:

Iterable<Map.Entry<String,String>>

public class SiteConfiguration
extends AccumuloConfiguration

An AccumuloConfiguration which loads properties from an XML file, usually accumulo-site.xml. This implementation supports defaulting undefined property values to a parent configuration's definitions.

The system property "org.apache.accumulo.config.file" can be used to specify the location of the XML configuration file on the classpath. If the system property is not defined, it defaults to "accumulo-site.xml".

This class is a singleton.

Note: Client code should not use this class, and it may be deprecated in the future.
