Hi, thanks for answering, but I did find the answer out. I knew Hadoop did it, but I needed a reference. I found it in "Data-intensive Text Processing with MapReduce" in the page 25. I quoted here:
Data/code co-location: . . . "An important optimization here is to prefer nodes that are on the same rack in the datacenter as the node holding the relevant data block, since inter-rack bandwidth is significantly less than intra-rack bandwidth." Thanks again. Renato M. 2010/8/9 vaibhav negi <[email protected]> > Hi , > > I am also a nebie to hadoop.
