hi everyone, i have to chain multiple map reduce jobs < actually 2 to 4 jobs >, each of the jobs depends on the o/p of preceding job. In the reducer of each job I'm doing very little < just grouping by key from the maps>. I want to give the output of one MapReduce job to the next job without having to go to the disk. Does anyone have any ideas on how to do this?
Thanx.
