Hadoop – HDFS Overview

Hadoop – HDFS Overview

Hadoop File System was developed using distributed file system design. It is run on commodity hardware. Unlike other distributed systems, HDFS is highly faulttolerant and designed using low-cost hardware. HDFS holds very large amount of data and provides easier access. To store such huge data, the files are stored across multiple machines. These files are … Continue reading Hadoop – HDFS Overview

An introduction to the Hadoop Distributed File System

Introduction HDFS is an Apache Software Foundation project and a subproject of the Apache Hadoop project. Hadoop is ideal for storing large amounts of data, like terabytes and petabytes, and uses HDFS as its storage system. HDFS lets you connect nodes (commodity personal computers) contained within clusters over which data files are distributed. You can … Continue reading An introduction to the Hadoop Distributed File System
