HDFS(Hadoop Distributed File System) is designed to run on commodity hardware – Low cost hardware

HDFS(Hadoop Distributed File System) is designed to run on commodity hardware – Low cost hardwareThe Hadoop Distributed File System (HDFS) is a distributed file system designed to run on commodity hardware. It has many similarities with existing distributed file systems. However, the differences from other distributed file systems are significant. HDFS is highly fault-tolerant and is designed to be deployed on low-cost hardware. HDFS provides high throughput access to application data and is suitable for applications that have large data sets. HDFS relaxes a few POSIX requirements to enable streaming a...

Hadoop MapReduce is a software framework for processing vast amounts of data in-parallel on large clusters

Hadoop MapReduce is a software framework for processing vast amounts of data in-parallel on large clustersHadoop MapReduce is a programming model and software framework for writing applications that rapidly process vast amounts of data in parallel on large clusters of compute nodes. In other words, Hadoop MapReduce is a software framework for easily writing applications which process vast amounts of data (multi-terabyte data-sets) in-parallel on large clusters (thousands of nodes) of commodity hardware in a reliable, fault-tolerant manner. A MapReduce job usually splits the input data-set into independent chunk...

Apache Hadoop is designed to scale up from single servers to thousands of machines

Apache Hadoop is designed to scale up from single servers to thousands of machinesThe Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using a simple programming model. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-availabile service on top of a cluster of computer...
