Hi, I want to be able to control the number of nodes assigned to a MR job on the cluster. For example, I want the job to not execute more than 10 Mappers at a time, irrespective of whether there are more nodes available or not.
I don't wish to control the number of mappers that are created by the job. The number of mappers is tied to the problem size / input data and on my input splits. I want it to remain that way. Is this possible? If so, what's the best way to do this? Deepak
