It's been great -- setup was a bit of work (we're on Ubuntu, so had to build from source), but once up and running it's allowed us to do lots of ad-hoc analysis that would have been too hard otherwise.

I've been meaning to write a MoSQL equivalent for our Impala data, but at the moment we're doing a more traditional ETL.

gdb - If you have Impala, Hadoop, and Hive right now. Why use MongoDB instead of HBase and make it all work in a happy harmony?

Awesome! Great to hear it's working out for you guys, looking forward to MoSQL for Impala :-)
