Learn what Hadoop is and how it can be used to store and process large amounts of data. Understand the basics of Hadoop, its components, and benefits.
2015.4.11 0.10版本发布 Apache Mahout introduces a new math environment we call Samsara, for its theme of universal renewal. It reflects a fundamental rethinking of how scalable machine learning algorithms are built and customized. Mahout-Samsara is here to help people create their own math while ...
This blog provides an in-depth overview of HDFS, including its architecture, features, and benefits. It also includes tutorials on how to use HDFS for big data applications.

This allows the dataset to be processed faster and more efficiently than it would be in a more conventional supercomputer architecture that relies on a parallel file system, where computation and data are distributed via high-speed networking. The base Apache Hadoop framework is composed of the ...
includeMapReduceand other such platforms where a large storage based on commodity hardware is required. The system is optimized for storage of very large files,high availabilityand reliability of data. This section gives an overview of HDFS with details of its architecture and API for accessing it...

承接上一篇翻译的HDFS的博客。这篇博客翻译自 https://www.edureka.co/blog/apache-hadoop-hdfs-architecture/ 介绍 在这篇博客里,我将介绍Apache Hadoop HDFS的架构。如果想熟练掌握Hadoop,HDFS&YARN是两个很重要的概念。在上一篇博客中,你已经知道了HDFS是一个分布式文件系统,部署在廉价的硬件上。现在,... ...
There are Secondary NameNodes, for failure tolerance, and Federated NameNodes, for larger systems in the current Hadoop architecture. The NameNode is the master process for HDFS. It works by keeping its metadata, such as block-to-file mapping, mainly in memory, so it can require a sizable...
While Hadoop is coded in Java, other languages—including C++, Perl, Python and Ruby) enable its use in data science. Processing speed HDFS uses a cluster architecture to help deliver high throughput. To reduce network traffic the Hadoop file system stores data in DataNodes where computations ...
