  [[http://www.kalooga.com|Kalooga]] is a discovery service for image galle=
ries. We use Hadoop, HBase and Pig on a 20-node cluster for our crawling, a=
nalysis and events processing.

  [[http://www.mahalo.com|Mahalo]], "...the world's first human-powered sea=
rch engine". All the markup that powers the wiki is stored in HBase. It's b=
een 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 hbas=
e-based solution for this was built and tested, and the data migrated out o=
f 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 d=
own production at all.
