Hadoop and Big Data Over View

Hadoop is a free open-source software framework for storing data and running applications on clusters of commodity hardware. It provides all-powerful storage for any nice of data, omnipotent supervision power and the doing to handle just about limitless concurrent tasks or jobs.
How Is Hadoop Being Used?
Going far away and wide ahead than its indigenous mean of searching millions (or billions) of web pages and returningrelevant results, many organizations are looking to Hadoop as their neighboring-door gigantic data platform. Popular uses today include:

1.Low-cost storage and data archive   

2.Sandbox for discovery and analysis        

3.Data lake        

 4.Complement your data warehouse 

 5.IoT and Hadoop

Hadoop is a easy to get praise of to, Java-based programming framework that supports the paperwork of large data sets in a distributed computing setting. It is share of the apache project sponsored by the Apache Software Foundation.                                                                                         Hadoop makes it realizable to run applications harshly speaking systems gone thousands of nodes involving thousands of terabytes. Its distributed file system facilitates trenchant data transfer rates together along in the company allows the system to continue operating uninterrupted in deed of a node failure. This associations  the risk of catastrophic system failure, though a significant number of nodes become inoperative.  Hadoop was inspired by Google's MapReduce and software framework in which an application is blinking beside into numerous little parts. Any of these parts (furthermore known as fragments or blocks) can be counsel in version to any node in the cluster. Doug Cutting, Hadoop's creator and named the framework after his child's stuffed toy elephant. The current Apache Hadoop eco system consists of the Hadoop kernel Map Reduce the Hadoop distributed file system (HDFS) and a number of associated projects such as Apache Hive, HBase and Zookeeper.            

The Hadoop is framework used by major players including Google, Yahoo and IBM, largely for applications involving search engines and advertising. The operating systems are Windows and Linux but Hadoop can moreover undertaking subsequent to BSD and OS X.
