Cloudera and Open Source

Apache Hadoop’s success is largely due to being an open source platform, thus a strong commitment to the open source community is a central and important part of Cloudera’s business.

Cloudera's Commitment to Open Source

  • CDH, Cloudera’s enterprise-ready distribution of Apache Hadoop and related projects, is 100% open source and Apache licensed. 
  • More than 50% of code produced by Cloudera is contributed upstream to open source projects via the many Cloudera engineers who serve as committers or contributors on those projects (see partial list below). 
  • More than 70% of Hadoop Stack-related issues assigned to distribution vendors are either closed or resolved by Cloudera committers.  
  • Cloudera employees were the founders of several important ecosystem projects, including Bigtop, Flume, Oozie, Whirr, Crunch (incubating), and Hadoop itself
  • Cloudera's chief architect Doug Cutting, founder of the Hadoop project, serves on the board, and is the current chairman, of the Apache Software Foundation.
