Abstract

Over the past decade, many technological solutions have been designed to meet the multiple challenges of Big Data, namely the problematic of storing and processing huge volumes of data generated at continuous pace. Two major concepts are at the heart of the solutions designed to meet the challenges: storage in distributed architecture and parallelized processing. HADOOP is one of the first frameworks that implemented this approach. In this document, we provide a general overview of the HADOOP framework, its main functionalities as well as some technological layers that form its ecosystem. First, we present the basic components of HADOOP technology: HDFS, MAPREDUCE and YARN. And secondly, we present some tools that allow exploiting data stored in HADOOP environment. Especially, we present HIVE a query engine, HBASE a distributed database, KAFKA a tool of ingestion and integration of streams of data and SPARK a parallelized data processing engine.
