I wrote up a pig-centric tutorial about how to get started collecting data
with Avro, processing it with Pig and publishing it with Voldemort/Sinatra:

I hope it may be helpful for some.  There is actually no Hadoop in the
intro, as it wasn't neccessary to get started using the tools to build
things - albeit on smaller data ;)  Still, its nice to pick a set of tools
and processes that will scale to hell and back, and then not worry about
switching platforms later.
