The internet and social media has given a big raise to business. Huge amount of data is being generated and collected by the companies and this large amount of data needs to process efficiently and effectively in order to get competitive advantages. Most of well-known companies have decided to choose Hadoop for their data management predicaments. Apache Hadoop is a framework that is used to run applications on large clustered hardware (servers). It is designed to scale up from a single server to thousands of machines, with a very high degree of fault tolerance.
Hadoop is more reliable than ordinary software to detect and handle failure. Hadoop makes the analytics much easier considering the terabytes of Data. The market for Hadoop is projected to rise from a $1.5 billion in 2012 to an estimated $16.1 billion by 2020 as per a report by Allied Market Research.
Hadoop was created by Doug Cutting and Michael J. Cafarella. It was named by Doug after his son’s stuffed toy elephant and is now being managed by Apache Software Foundation. The Hadoop architecture is made up of the Hadoop Common, Hadoop distributed file system (HDFS) and a MapReduce engine. MapReduce and HDFS are designed to handle any node failures. The architecture distributes data into chunks across many servers for the programmers to easily analyze and visualize easily.
MapReduce: Hadoop MapReduce is a software framework or parallel programming model for easily writing applications which process vast amounts of data in-parallel on large clusters of commodity hardware in a reliable, fault-tolerant manner. Map Reduce is designed in such a way that any failure can automatically be taken care by the framework itself.
HDFS- Hadoop Distributed File System. Basically, it is a storage system used by Hadoop. It spans all the nodes in a Hadoop cluster for data storage. It links together the file systems on many local nodes to make them into one big file system. Hadoop Distributed File System assumes nodes will fail, so it achieves consistency or reliability by replicating data across numerous nodes.
The prominent feature of Hadoop MapReduce that makes it favorite of large enterprises and organization is its high fault tolerance power, which means if any of the nodes fail in the environment, the enterprise data management system won’t face any halt and it will run as smoothly as it was running before. This is because the architecture takes care of allocating and reproducing the data efficiently through numerous nodes. Furthermore, Easy implementation can use only two servers to perform the tasks, but the single one may scale up to hundreds of servers without putting extra effort.
Every existing server in Hadoop applications provides local storage and multiplication, which means, if somebody runs some query contrary to huge sets of data; every server in this circulated architecture will be executing the query on its local machine contrary to the data sets present locally. Resultantly, the final set of all these local servers is incorporated.
Hadoop is cost effective and a powerful data management solution. You do not necessarily require a powerful server while using Hadoop. You can also use some less expensive commodity servers as individual notes and perform the task. This will diminish the chances of any further confusion and also helps organization to manage better and faster, without a powerful server.
Hadoop applications are so much beneficial for your business. Hadoop architecture can be a significant way to manage various tasks of your business. For web search service, for data mining, for sorting, for machine learning and for various other systems, Hadoop comes with strong functionality and implementations.
