Hadoop newbie here. I wrapped my company's entity extraction product in a Hadoop task, and give it a large file of the magnitude of 100MB. I have 4 VMs running on a 24-core CPU server, and made two of them the slave nodes, one namenode and another job tracker. It turned out that processing the same data size takes longer using Hadoop than processing it in serial.
I am curious that how I can experience the advantage of Hadoop. Is having many physical machines essential? Would I need to process Terabytes of data? What would be the minimum set up where I can experience the advantage of Hadoop? ---- T. "Kuro" Kurosaka
