Can someone give me a direction on how to start a map reduce based on an outcome of another map reduce? ( nothing common between them apart from the first decides about the scope of the second.
I might also want to set the scope of my second map reduce (from/after) my first map reduce(scope as in scan(start,stop) typically data comes in a few tables for us and we start crunching it and then adding some more data to man tables like info etc to get rid of table joins. a light weight framework will do better than a typical workflow management tool. thanks, Vishal Kapoor
