It runs on something called Hadoop, an open-source data-management software service that is useful for companies that store enormous amounts of data and have to regularly index it.
Accel Partners, Greylock Partners, In-Q-Tel and Meritech Capital Partners all participated in the most recent funding round. It has raised $76 million to date.
Cloudera got started back in 2008, when an engineer named Jeff Hammerbacher quit his fancy job at Facebook.
