Introduction to Big Data Hadoop
Big data is a collection of enormous datasets that cannot be processed by using traditional computing techniques. It is not one technique or a tool, rather it’s become a whole subject, that involves different tools, techniques and frameworks.
Hadoop is an Apache open source framework written in Java that permits the distributed process of enormous datasets across clusters of computers using easier programming models. The Hadoop framework application works in an environment that gives distributed storage and computation across clusters of computers. Hadoop is meant to be scaled up from a single server to thousands of machines, each offering local computation and the storage.
The Benefits of Big Data are:
•Utilize the information kept in the social network like Facebook, the marketing agencies are learning about the response for their campaigns, promotions, and other advertising mediums.
•Make use of the information in the social media like preferences and product perception of their consumers, product companies and retail organizations are planning their production.
•Utilize the information regarding the previous medical history of patients, hospitals are providing better and quick service.
Hadoop Architecture
MapReduce: MapReduce may be a parallel programming model for writing distributed applications devised at Google for systematic process of enormous amounts of information (multi-terabyte data-sets), on massive clusters (thousands of nodes) of commodity hardware in a reliable and fault-tolerant manner. Then, the MapReduce program runs on Hadoop which is an Apache open – source framework.
Hadoop Distributed File System: The Hadoop Distributed File System (HDFS) relies on the Google File System (GFS) and provides a distributed file system that is designed to run on commodity hardware. It has several similarities with existing distributed file systems. However, the variations from different distributed file systems are more significant. It is extremely fault-tolerant and is designed to be deployed on low-price hardware. It gives high throughput access to application information and is appropriate for applications having massive datasets.
Hadoop framework additionally includes the subsequent two modules
•Hadoop Common: These are Java libraries and utilities required by alternative Hadoop modules.
•Hadoop YARN: Hadoop yarn may be a framework for job scheduling and cluster resource management.
Latest trends and Developments of Big data Hadoop
Hadoop remains a center innovation for a few endeavors. Together, Cloudera and Hortonworks have the capability to offer customers more thorough arrangement of services and offerings, for instance, an end-to-end cloud big data giving and support for more complex and critical organizations. Be that as it could, the technology world keeps on moving quickly, and numerous organizations will as of now be looking past the Hadoop innovation.
However, big data is progressively the tools that set businesses apart. People who will harvest targeted insights from a big data solution gain a key favorable position; organizations unfit to use this innovation can fall behind. Indeed, even as Hadoop develops, there keeps on being big data solutions that far outmatch it at a higher price for the individuals who require more noteworthy ability. The ultimate fate of Hadoop and big data will contain a large number of technologies all combined and coordinated.
Market Share of Big data Hadoop
Considering the current state of big data, a tremendous quantity of information is generated daily, that too in the form of heterogeneous databases. Around 90 percent of data generated across the world was created over the last couple of years. As this immense volume of data is unstructured and kept in community servers, it is very difficult to manage this data and derive insightful data out of it.
Thus, the rise of big data and growing need for big data analytics is driving the adoption of Hadoop technology. Hadoop changes the political economics and dynamics of large-scale computing of information as a result of it’s value effective, scalable, flexible and fault tolerant. The technology is exclusive and may be integrated into companys’ existing goods servers and storage devices to conduct massively parallel computing. New nodes will be added when needed without changing the existing data formats.
Based on the part, the services segment of the market is calculable to grow at the highest CAGR during the forecast period. This high growth of the services phase may be attributed to the increasing need for services related to the rising adoption of Hadoop Big data solutions by various enterprises. The Consulting and Development services sub-segment of the Hadoop Big data analytics market would grow at the highest CAGR during the forecast period. Consulting and Development Services are helping to simplify complex big data solutions for better business decisions. As per the recent analysis, It has the market share of 45.36 percent. Big Data Hadoop Developer Professionals are paid around $139,000.
