"IT168" with the increasing demand for large data solutions, Apache Hadoop has quickly become one of the preferred platforms for storing and processing massive, structured, and unstructured data. Businesses need to deploy this open-source framework on a small number of intel® xeon® processor-based servers to quickly start large data analysis with lower costs. The Apache Hadoop cluster can then be scaled up to hundreds of or even thousands of nodes to shorten the query response time of petabytes to the second.
