What is the Hadoop ecosystem? Https://www.facebook.com/Hadoopers In some articles and examples of Teiid, there will be information about the use of Hadoop as a Data source through Hive. When you use a Hadoop environment to create Data Virtualization examples, such as Hortonworks Data Platform and Cloudera Quickstart, there will be a large number of open-source projects. This article mainly gives a preliminary understanding of

Transferred from: http://www.csdn.net/article/2015-06-25/2825056 Summary: Tachyon separates the functions of memory storage from spark so that spark can focus more on the computation itself, in order to achieve higher execution efficiency through a finer division of labor. Tachyon is a fast-growing new project within the spark ecosystem. In essence, Tachyon is a distributed memory file system that reduces spark memory pressure while giving spark memor

Ctrip handles a large number of requests every day, from initiation to arrival to the server, in addition to a large number of network hardware, but also through a number of application layer middleware framework.These middleware frameworks include APIGATEWAY,SLB soft load, SOA service invocation framework, RPC invocation framework, and so on. There are a wide variety of requests, from users and from various partners, HTTP, TCP, demand-friendly, high-performance, and different security and permi

Big data itself is a very broad concept, and the Hadoop ecosystem (or pan-biosphere) is basically designed to handle data processing over single-machine scale. You can compare it to a kitchen so you need a variety of tools. Pots and pans, each have their own use, and overlap with each other. You can use a soup pot directly as a bowl for dinner, and you can peel it with a knife or plane. But each tool has its own characteristics, although strange combi
