How does Hadoop work?

Instead of using one large computer to store and process data, Hadoop uses clusters of multiple computers to analyze massive datasets in parallel. Hadoop can handle various forms of structured and unstructured data, which gives companies greater speed and flexibility for collecting, processing, and analyzing big data than can be achieved with relational databases and data warehouses.

What is Hadoop used for?

Analytics and big data. A wide variety of companies and organizations use Hadoop for research, production data processing, and analytics that require processing terabytes or petabytes of big data, storing diverse datasets, and data parallel processing.

What are the benefits of Hadoop?

In the Hadoop ecosystem, even if individual nodes experience high rates of failure when running jobs on a large cluster, data is replicated across a cluster so that it can be recovered easily should disk, node, or rack failures occur.

Why do you need Hadoop?

Apache Hadoop was born out of a need to more quickly and reliably process an avalanche of big data. Hadoop enables an entire ecosystem of open source software that data-driven companies are increasingly deploying to store and parse big data. Rather than rely on hardware to deliver critical high availability, Hadoop’s distributed nature is designed to detect and handle failures at the application layer, delivering a highly available service on top of a cluster of computers to reduce the risks of independent machine failures.

What is Apache Hadoop?

Apache Hadoop software is an open source framework that allows for the distributed storage and processing of large datasets across clusters of computers using simple programming models.
