Tag: HDFS
With growing data velocity the data size easily outgrows the storage limit of a machine. A solution would be to store the data across a network of machines. Such filesystems are called distributed filesystems. Since data is stored across a network all the complications of a network come in. /certifications/ This is where Hadoop comes … Continue reading Introduction to Hadoop Distributed File System(HDFS)
Before head over to learn about the HDFS(Hadoop Distributed File System), we should know what actually the file system is. The file system is a kind of Data structure or method which we use in an operating system to manage file on disk space. This means it allows the user to keep maintain and retrieve … Continue reading Hadoop – HDFS (Hadoop Distributed File System)

The Hadoop Distributed File System (HDFS) is a distributed file system. It is a core part of Hadoop which is used for data storage. It is designed to run on commodity hardware. Unlike other distributed file system, HDFS is highly fault-tolerant and can be deployed on low-cost hardware. It can easily handle the application that … Continue reading HDFS Features and Goals
Introduction The data researchers no longer depend only on interviews, surveys, observational studies to collect data. Instead, they have switched to the faster ways of data collection which includes leveraging internet, cameras, smartphones, drones, bots and many more. Later, the collected data is used by organization / governments to make business decisions. But, before that, … Continue reading Getting Started with Big Data Integration using HDFS and DMX-h
