In this post, we will look into the core components of Hadoop and find out their role. There are two major concepts for us to understand in Hadoop. Once you understand these, you will start understanding why Hadoop works the way, it does. These concepts are related to HDFS and Map Reduce. At a very high level, HDFS handles storage and Map Reduce does fast computing.
I do not know about you, but when I look at any building or technology, I always wonder, what was going through the designers and architects thought. Why they decided to pick one route over another. With this in mind, in next few posts, I will be exploring Hadoop Architecture.
