Examples 1 and 2 require that the file MaxMindLite.jar be installed on the Aster Database. This jar file contains the converter interface used in these examples, 'com.asterdata.sqlmr.analytics.location.ipgeo.MaxMindLite'.
Example 3 uses the default Converter class that ships with the ipgeo function (geolite 1.2.8).
The function requires two database files that map ip addresses to geographic locations (GeoLiteCity.dat and GeoLiteCityv6.dat). In Example 1, the files are referenced by pathname using the argument IpDatabaseLocation, and need not be installed on the Aster Database. Examples 2 and 3 assume that the two database files have been installed on the Aster Database.
