Hi, I'm trying to write a map/reduce job in ruby. Does anyone have an example of the ruby code? I've seen the word count example written in python but it looks to me that it's a different scenario... where the code is actually being compiled and put in a jar first.
More precisely, I'm working with nutch which means that from within my ruby code I need to access data using nutch's java classes. JRuby can access the Java classes and hadoop-streaming in supposed to be able to execute map/reduce code written in any language... what I don't understand is what goes in between (especially how the ruby code would receive the arguments... for the output I guess it's just a matter of calling output.collect() like usual). thx, Sebastien p.s. an example in another language is also welcomed... I can translate it.
