Subject What is the class that launches the reducers?
Date Thu, 25 Aug 2016 19:18:14 GMT
I am trying to implement a mechanism in MapReduce v2 that allows to suspend
and resume a job. I must suspend a job when all the mappers finish, and
resume the job from that point after some time. I do this, because I want
to verify the integrity of the map output before executing the reducers.

I am looking for the class that tells when the Reduce tasks should start.
Does anyone know where is this?
