Subject Chaining Multiple Map reduce jobs.
Date Wed, 08 Apr 2009 21:30:15 GMT
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?
