Hadoop: MaxMind GeoIP lookup from Distributed Cache

Place GeoCityLite.dat in HDFS:

• Create a JobClient Object and add the files' URI to the distributedCache.

• Create a configure method that overrides org.apache.hadoop.mapred.MapReduceBase and org.apache.hadoop.mapred.jobConfigurable

create a Location Object and pass the IP to it.
A significant IPs might come back with a null city/ country. Use try and catch blocks to catch exceptions and process them accordingly.




Notes:

Reduce the creation of the LookupService objects. These are resource intensive.
Similarly, reduce the creation of Location Objects.
