We are using CDH4.2 and have had a very positive experience so far.

Cloudera has in fact been an inspiration for us to follow, you guys have really struck the right balance between open source and commercial support. We follow the same philosophy with Scrapy (an open source web crawling framework), as you do with Hadoop and its ecosystem.
