I am trying to run some simple example of Spring Hadoop (Spring Data).I ran a hadoop Map Reduce program of word count on a hadoop cluster.Now I want to run this from Spring Hadoop. I did not get any example on internet and tried to run Word Count given in Spring Data documentation but could run it. Where can i find simple steps to run Spring Hadoop( Map Reduce program from Spring)? in Spring Hadoop we specify the mapper and reducer in the XML configuration but where to place the Mapprer java Class and Reducer Java Class and Driver class?where to keep these? Suppose I have a cluster where I am running Map Reduce word count progam.Now I want to convert this Map Reduce prgram (Mapper,Reducer,Driver classed) to run from Spring?
