Prashant Kommireddi commented on PIG-2456:
------------------------------------------

These property files are key-value pairs, I believe declaring an alias is not 
supported.

Here are a couple JIRAs around pig configs, 
https://issues.apache.org/jira/browse/PIG-111 and 
https://issues.apache.org/jira/browse/PIG-1381
You could also take a look at PropertiesUtil.loadDefaultProperties(Properties)
{code}
public static void loadDefaultProperties(Properties properties) {
        loadPropertiesFromFile(properties,
                System.getProperty("user.home") + "/.pigrc");
        loadPropertiesFromClasspath(properties, DEFAULT_PROPERTIES_FILE);
        loadPropertiesFromClasspath(properties, PROPERTIES_FILE);
        setDefaultsIfUnset(properties);
        
//foo..
{code}
