Hadoop is an open source, distributed, Java-based software framework that is developed by the Apache Foundation. Hadoop allows users to develop distributed programs and make full use of cluster capacity for high-speed computing and storage without the need to understand the underlying details of the...
Apache Hadoop is an open-source software framework that provides highly reliable distributed processing of large data sets using simple programming models.
ApacheHadoopis an open-source framework that is suited for processing large data sets on commodity hardware. Hadoop is an implementation ofMapReduce, an application programming model developed by Google, which provides two fundamental operations for data processing:mapandreduce. The former transforms and...
Hadoop is an open-source framework that allows to store and process big data in a distributed environment across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. ...
Apache Spark— which is also open source — is a data processing engine for big data sets. Like Hadoop, Spark splits up large tasks across different nodes. However, it tends to perform faster than Hadoop and it uses random access memory (RAM) to cache and process data instead of a file...
ST-Hadoop is an open-source MapReduce extension of Hadoop designed specially to analyze your spatio-temporal data efficiently - lmarabi/st-hadoop
官方原文: Chukwa is an open source data collection system for monitoring large distributed systems. Chukwa is built on top of the Hadoop Distributed File System (HDFS) and Map/Reduce framework and inherits Hadoop’s scalability and robustness. Chukwa also includes a flexible and powerful toolkit...
Apache Hadoop ist ein Open-Source-Framework, das verwendet wird, um große Datensätze mit Datenmengen im Bereich von Gigabytes bis zu Petabytes zu speichern und zu verarbeiten. Anstatt mit einem einzigen Computer die Daten zu speichern und zu verarbeiten, können Sie mit Hadoop mehrere Com...

The world of big data contains a large and vibrant ecosystem, but one open source project reigns above them all, and that’s Hadoop. Hadoop is the de facto standard for distributed data crunching. You’ll find a great introduction to Hadoop atbit.ly/PPGvDP: “Hadoop provides a MapReduce ...
