Definition - What does Apache Hadoop mean?
Apache Hadoop is a freely licensed software framework developed by the Apache Software Foundation and used to develop data-intensive, distributed computing.

A central Hadoop concept is that errors are handled at the application layer, versus depending on hardware for reliability.
