Re: In MapReduce Ideally how many maps should be configured on a slave

The configuration of the slave i.e. number of core and RAM available on the slave. The right number of map/node can between 10-100. Usually, 1 to 1.5 cores of processor should be given to each mapper . So for a 15 core processor, 10 mappers can run.
