Added GumGum as service powered by HBase

  [http://www.adobe.com Adobe] - We currently have about 30 nodes running HDFS, Hadoop and HBase  in clusters ranging from 5 to 14 nodes on both production and development. We plan a deployment on an 80 nodes cluster. We are using HBase in several areas from social services to structured data and processing for internal use. We constantly write data to HBase and run mapreduce jobs to process then store it back to HBase or external systems. Our production cluster has been running since Oct 2008.
  
  [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 production cluster with billions of rows over several tables.

+ [http://gumgum.com GumGum] is an analytics and monetization platform for online content. We've developed usage-based licensing models that make the best content in the world accessible to publishers of all sizes.  We use HBase 0.20.0 on a 4-node Amazon EC2 cluster to record visits to advertisers in our ad network. Our production cluster has been running since July 2009.
  
  [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.
