Hadoop – the poster child for Big Data
The perception of handling Big Data especially the unstructured data is being changed by Hadoop. Let’s know how Apache Hadoop software library plays a vital role in handling Big Data. Using simple programming models Apache Hadoop enables surplus data to be streamlined across clusters of computers. Since Hadoop is open source and it can also run on commodity hardware, there is dramatic initial cost savings and it continues to grow as your organizational data grows. Additionally, a robust Apache community behind Hadoop continues to contribute to its advancement. It truly is made to scale up from single servers to a large number of machines, local computation and storage space is offered by each and every nodes. Instead of depending on hardware to provide high-availability, at the application layer the library is built to detect and handle breakdowns.
