Hadoop is listed as an open-source Apache project, however, the main commercial distribution packages were coming from Hortonworks and Cloudera. It happened so that most of Hadoop original developers went to Hortonworks, while one of the main co-creators – Doug Cutting – joined Cloudera.
For almost eight years the two companies rivaled with each other for a reason that does not seem to be a valid cause for a rivalry:
Now, the two teams are one company.
This merger had been long overdue. A viable software platform has to evolve along both its performance metrics and its usability index. Hadoop users will definitely benefit from the merger as the product should be improving faster without any waste of resources on rivalry. It could be just a little too late – too many Hadoop competitors have sprung onto the market, but there’s still hope as the market for big data software is still growing fast.
