This section covers some of the operational mechanics of running an application that uses Cascading with the Hadoop platform, including building the application jar file and configuring the operating mode.

To use the HadoopFlowConnector (i.e., to run in Hadoop mode), Cascading requires that Apache Hadoop be installed and correctly configured. Hadoop is an Open Source Apache project, freely available for download from the Hadoop website, http://hadoop.apache.org/core/.
