Question

Is CDH(Cloudera Distribution for hadoop) is open source to use or is it commercial?

Any inputs on this greatly appreciated.

Answer 1

"All software developed by Cloudera for CDH is released with an Apache 2.0 license".

In other words, it is open source.

Answer 2

Cloudera contributes to apache hadoop in many ways. Some of them are open source and free to use and some are not open source and commercial.

Cloudera adds their own features to base apache hadoop (eg: human readable option in hadoop file system commands: "hadoop fs -df -h" , "hadoop fs -du -h" and a lot more.. ) these are open source under apache license.

Cloudera manager is the hadoop management tool from cloudera for managing hadoop eco systems which is not open source and available in free editions and enterprise editions.
