Some hacking info on
cascading.jruby can be packaged as a gem. To do so, you must generate the necessary packaging files:
jruby -S rake gem
will produce the gem in the pkg/ sub-directory. After that, just cd to this directory and:
jruby -S rake install cascading.jruby-xxx.gem
Cascading::Operations module is mixed-in the
Cascading::Assembly class to provide some shortcuts for common operations.
The file cascading/cascading.rb defines global helper methods for cascading like tap creation, fields creation, etc.
