cascading.jruby is a small DSL above Cascading.
It requires Hadoop (>= 0.18.3) and Cascading (>=1.0.1) to be set via the environment variables: HADOOP_HOME and CASCADING_HOME
In order to use the extensions for Cascading.hbase and Cascading.jdbc, the following variables should be set as well: CASCADING_HBASE_HOME and CASCADING_JDBC_HOME
