When running an MR job/program assuming there r 'n' (=100) Mapperstriggered
then my question is will the setup & cleanup run n number of times which means
once for each mapper or for all the mappers they will run only once.
Any help is appreciated.
Thanks
Sai
Assuming you speak of MRv1 (1.x/0.20.x versions), there is just 1 Job
Setup and 1 Job Cleanup tasks additionally run for each Job.
