Apache Hadoop ecosystem continues to evolve at a rapid pace with newer projects that are being added as incubators while those currently under incubation are getting ready to graduate out. Let’s visit the current state of open source Apache Hadoop ecosystem.

About the categorization:
(1) Core Layers – this category comprises the core components which are required in part or as a whole to optimally leverage Apache Hadoop
(2) Atmospheric Layers – this category comprises the additional components which provide advanced capabilities and insights for the composite use cases.
The nomenclature adopted for categories (core/atmospheric) and layers does not constitute official lingo and are being introduced to demarcate the basic use case versus advanced use cases of Apache Hadoop. As Hadoop distribution matures out along with technology stacks built up by organizations, we expect components and probably even layers to move around from one category to other.
Other open source projects/components like Cloudera Impala, Kerberos, Protocol Buffer etc. are not included in this ecosystem diagram since they are not Apache Software Foundation (ASF) projects.
