HDFS
What is HDFS ? Before discussing HDFS, let us first discuss Scalability The primary benefit of Hadoop is its Scalability. One can easily scale the cluster by adding more nodes. There are two types of Scalability in Hadoop: Vertical and Horizontal Vertical Scalability - It is also referred as “scale up”. In vertical scaling, you can increase the hardware capacity of the individual machine. In other words, you can add more RAM or CPU to your existing system to make it more robust and powerful. Horizontal Scalability - It is also referred as “scale out” is basically the addition of more machines or setting up the cluster. In horizontal scaling instead of increasing hardware capacity of individual machine you add more nodes to existing cluster and most importantly, you can add more machines without stopping the system. HDFS HDFS stand for Hadoop Distributed File Storage. HDFS provides better data throughput than traditional file systems. It provides a way to man...
