Hadoop 3.0 Cloudera

Hadoop 3.0 Cloudera (or CDH 6.x) is an obvious question after you have seen Hadoop 3.0 new feature and enhancement list. At the time of writing this blog, CDH was having 5.14 supporting Hadoop 2.7.3. Hadoop 3.0 has lot of changes and if you want to try it in stand alone mode before it becomes available, it is available for installation. Since the changes in Hadoop 3.0 is quite a lot compare to Hadoop 2.0, it would take time for companies like Cloudera or Hortonworks to make a production ready bundle for it.

Hadoop 3.0 GA was released on 14 Dec 2017 and if you follow the Hadoop 3.0 architecture, you may find very interesting changes which will certainly take few months for bundler to give next major release.

Most of the organization is now running enterprise data lake at their premises and storage cost reduction is one of the promising feature, Hodoop 3.0 Cloudera or CDH 5.14 must arrive as soon as possible.

Hadoop 3.0 Cloudera Vs CDH 5.14

Hortonworks approach is to provide new bundling for minor version only when necessary  to ensure that the interoperability of Apache project components. Following are the HDP components including the package version which are included in HDP 2.6.4. The list of Hadoop 3.0 Cloudera support is yet to be available.
