from the article Many are aware of Facebook’s Cassandra system, but now they’ve built something new called hBase (working alongside the open source community again)

Someone knows what this means? Did they switch to hbase the _existing for many years_ database solution, or did they build something else on top of it (is there a trace of this in the hbase community?) or did they build something else from scratch and incredibly hit on the same name?

I wish techcrunch was a bit less.. techcrunch...
