-- This is a Hive program. Hive is an SQL-like language that compiles
-- into Hadoop Map/Reduce jobs. It's very popular among analysts at
-- Facebook, because it allows them to query enormous Hadoop data
-- stores using a language much like SQL.
-- Our logs are stored on the Hadoop Distributed File System, in the
-- directory /logs/randomhacks.net/access. They're ordinary Apache
-- logs in *.gz format.
