Cloudera Inc. is an American-based software company that provides Apache Hadoop-based software, support and services, and training to business customers.

Cloudera's open-source Apache Hadoop distribution, CDH (Cloudera Distribution Including Apache Hadoop), targets enterprise-class deployments of that technology. Cloudera says that more than 50% of its engineering output is donated upstream to the various Apache-licensed open source projects (Apache Hive, Apache Avro, Apache HBase, and so on) that combine to form the Hadoop platform. Cloudera is also a sponsor of the Apache Software Foundation.[2]


Three engineers from Google, Yahoo and Facebook (Christophe Bisciglia, Amr Awadallah and Jeff Hammerbacher, respectively) joined with a former Oracle executive (Mike Olson) to form Cloudera in 2008.[3] Olson was the CEO of Sleepycat Software, the creator of the open-source embedded database engine Berkeley DB (acquired by Oracle in 2006). Awadallah was from Yahoo, where he ran one of the first business units using Hadoop for data analysis.[4] At Facebook Hammerbacher used Hadoop for building analytic applications involving massive volumes of user data.[5]

Architect Doug Cutting, also a former chairman of the Apache Software Foundation, authored the open-source Lucene and Nutch search technologies before he wrote the initial Hadoop software in 2004. He designed and managed a Hadoop storage and analysis cluster at Yahoo! before joining Cloudera in 2009. Chief operating officer was Kirk Dunn.[6]

In March 2009, Cloudera announced the availability of Cloudera Distribution Including Apache Hadoop in conjunction with a $5 million investment led by Accel Partners.[7] In 2011, the company raised a further $40 million from Ignition Partners, Accel Partners, Greylock Partners, Meritech Capital Partners, and In-Q-Tel, a venture capital firm with open connections to the CIA.[8]

In June 2013 Tom Reilly became chief executive, although Olson remained as chairman of the board and chief strategist. Reilly was chief executive at ArcSight when it was acquired by Hewlett-Packard in 2010.[9] In March 2014 Cloudera announced a $900 million funding round, led by Intel Capital ($740 million), with additional funds coming from T Rowe Price, Google Ventures and others.[10]

Cloudera is headquartered in Palo Alto, California.

Products and services[edit]

Cloudera offers software, services and support in three different bundles:

  • Cloudera Enterprise includes CDH and an annual subscription license (per node) to Cloudera Manager and technical support. It comes in three editions: Basic, Flex, and Data Hub.
  • Cloudera Express includes CDH and a version of Cloudera Manager lacking enterprise features such as rolling upgrades and backup/disaster recovery.
  • CDH may be downloaded from Cloudera's website at no charge, but with no technical support nor Cloudera Manager.

All versions may be downloaded from Cloudera's website.

CDH contains the main, core elements of Hadoop that provide reliable, scalable distributed data processing of large data sets (chiefly MapReduce and HDFS), as well as other enterprise-oriented components that provide security, high availability, and integration with hardware and other software.[11]

In October 2012, Cloudera announced the Cloudera Impala project, an open-source distributed query engine for Apache Hadoop.[12]


  • In April 2010, Chief Scientist Jeff Hammerbacher was named a "Best Young Tech Entrepreneur" by Bloomberg BusinessWeek.[13]
  • In June 2012, received Morgan Stanley's "CTO Award for Innovation".[14]
  • In August 2012, CRN named Cloudera among the "The 25 Coolest Emerging Vendors For 2012".[15]
