output from one map reduce job as the input to another map reduce job?
Kevin Burton 2011-09-27, 19:09
Is it possible to connect the output of one map reduce job so that it is the
input to another map reduce job.

Basically… then reduce() outputs a key, that will be passed to another map()
function without having to store intermediate data to the filesystem.
