  [[http://www.flurry.com|Flurry]] provides mobile application analytics.  We use HBase and Hadoop for all of our analytics processing, and serve all of our live requests directly out of HBase on our 16-node production cluster with billions of rows over several tables.
  
  [[http://www.drawntoscaleconsulting.com|Drawn to Scale Consulting]] consults on HBase, Hadoop, Distributed Search, and Scalable architectures.

  [[http://www.mahalo.com|Mahalo]], "...the world's first human-powered search engine". All the markup that powers the wiki is stored in HBase. It's been in use for a few months now. !MediaWiki - the same software that power Wikipedia - has version/revision control. Mahalo's in-house editors produce a lot of revisions per day, which was not working well in a RDBMS. An hbase-based solution for this was built and tested, and the data migrated out of MySQL and into HBase. Right now it's at something like 6 million items in HBase. The upload tool runs every hour from a shell script to back up that data, and on 6 nodes takes about 5-10 minutes to run - and does not slow down production at all.
