Hadoop : The Definitive Guide – Book

For the developers, Cascading made it easy to start with a simple unit test (created by subclassing cascading.ClusterTestCase) that did simple text parsing and then to layer in more processing rules while keeping the application logically organized for maintenance. Cascading aided this organization in a couple of ways.

First, standalone operations (Functions, Filters, etc.) could be written and tested independently. Second, the application was segmented into stages: one for parsing, one for rules, and a final stage for binning/collating the data, all via the SubAssembly base class described earlier.
