Constructor Detail

ClientConfiguration

public ClientConfiguration(List<? extends org.apache.commons.configuration.Configuration> configs)

ClientConfiguration

public ClientConfiguration(org.apache.commons.configuration.Configuration... configs)

Iterates through the Configuration objects, populating this object.

See Also:

PropertiesConfiguration, loadDefault()

Method Detail

loadDefault

public static ClientConfiguration loadDefault()

Attempts to load a configuration file from the system. Uses the "ACCUMULO_CLIENT_CONF_PATH" environment variable, split on File.pathSeparator, for a list of target files. If not set, uses the following in this order- ~/.accumulo/config $ACCUMULO_CONF_DIR/client.conf -OR- $ACCUMULO_HOME/conf/client.conf (depending on whether $ACCUMULO_CONF_DIR is set) /etc/accumulo/client.conf A client configuration will then be read from each location using PropertiesConfiguration to construct a configuration. That means the latest item will be the one in the configuration.
