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 :-)

We've been pretty happy so far. There have been a few rough edges getting it up and keeping it running, but we've been very impressed with the performance so far.

I've passed your comment on to Colin, who wrote the Ruby client -- I'm sure he'll appreciate it!

I got myself a little Impala Herd server setup, pointed it at my Impala cluster and it's working great ;).

heh, I didn't think anyone would actually use that - I originally wrote it meaning to use it as a tutorial for the blog post, then scrapped that idea.

Thanks for the kind words!
