What is Hadoop PDF?
Table of Contents
Hadoop is an open-source framework that allows to store and process big data in a distributed environment across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage.
What is HDFS explain its components?
HDFS comprises of 3 important components-NameNode, DataNode and Secondary NameNode. HDFS operates on a Master-Slave architecture model where the NameNode acts as the master node for keeping a track of the storage cluster and the DataNode acts as a slave node summing up to the various systems within a Hadoop cluster.
What is Hadoop in simple words?
Hadoop is an open-source software framework for storing data and running applications on clusters of commodity hardware. It provides massive storage for any kind of data, enormous processing power and the ability to handle virtually limitless concurrent tasks or jobs.
What are the two major components of Hadoop?

Hadoop Distributed File System (HDFS) HDFS is the storage layer for Big Data; it is a cluster of many machines; the stored data can be used to process Hadoop.
What is the most difficult Hadoop component?
– Problem involved hardware faulty. – Problem involved 3rd party libraries crashes. – Customize algorithms that involves lots of mathematics. – GUI. Especially with C++. – Thinking the way to fit 4mb file to 2mb storage device. – When software cross platform and I am the one who develop for all platforms.
