Hadoop distributions
In the present day, Hadoop and its individual ecosystem components are complex projects. As we saw earlier in this chapter, Hadoop has a number of different forks or code branches over a large number of releases. There are also a lot of different distributions of Hadoop. The distribution with the most activity and community involvement is the one that resides as part of Apache Software Foundation. This distribution is free and has a very large community behind it. The community contributions to the Apache Hadoop distribution shape the general direction taken by Hadoop. Support in the Apache Hadoop distribution is via online forums, where questions are addressed to the community and answered by its members.
