Apache Components

VMware today unveiled the latest open source project--serengeti, which enables companies to quickly deploy, manage, and extend Apache Hadoop in virtual and cloud environments. In addition, VMware works with the Apache Hadoop community to develop extension capabilities that allow major components to "perceive virtualization" to support flexible scaling and further improve the performance of Hadoop in virtualized environments. Chen Zhijian, vice president of cloud applications services at VMware, said: "Gain competitive advantage by supporting companies to take full advantage of oversized data ...

Cloudera recently released a news article on the Rhino project and data at-rest encryption in Apache Hadoop. The Rhino project is a project co-founded by Cloudera, Intel and Hadoop communities. This project aims to provide a comprehensive security framework for data protection. There are two aspects of data encryption in Hadoop: static data, persistent data on the hard disk, data transfer, transfer of data from one process or system to another process or system ...

Currently, the Hadoop distribution has an open source version of Apache and a Hortonworks distribution (HDP Hadoop), MapR Hadoop, and so on. All of these distributions are based on Apache Hadoop.

Apache Tomcat's goal is to provide commercially-quality servers in an open and cooperative way based on the Java platform. (Official website: http://tomcat.apache.org/) Apache is a Web server that can be run on almost any widely used computer platform. Apache and Tomcat are independent and can be integrated on the same server. Tomcat is a Java application server, a servlet container that is an extension of Apache. Tomcat is an open ...

1. As with most other distributed systems, the Apache Mesos, in order to simplify the design, also employs a master/slave structure that, in order to solve the master single point of failure, makes master as lightweight as possible, and the above number It can be reconstructed through various slave, so it is easy to solve the single point of failure by zookeeper. (What is Apache Mesos?) Reference: "Unified resource management and scheduling platform (System) Introduction", this article analysis based on MES ...

1. The introduction of Mesos is mainly composed of four components, respectively, Mesos-master,mesos-save,scheduler and executor, each component is based on protocal buffer actor Model for communication (using Open Source Library libprocess). In other words, each module is a server (in fact, the socket server), listening to messages from other modules, once received a message ...

There are more articles on the Hadoop reference Design group components and critical steps, so the small set of Hadoop reference Design group components and key steps are divided into sections to give you a detailed introduction. Software operating system: Hadoop supports any operating system that can run the Java environment. In practical applications, the average customer will choose the 64-bit versions of different Linux distributions. In this reference design we chose the free enterprise-class Linux CentOS6.3 x64 version. Hadoop system: Hadoop is based on ...

"Editor's note" Recently, MAPR has formally integrated the Apache drill into the company's large data-processing platform, and opened up a series of large database-related tools. Today, in the highly competitive field of Hadoop, open source has become a tool for many companies, they have to contribute more code to protect themselves, but also through open source to attack other companies. In this case, Derrick Harris made a brief analysis on Gigaom. Recently, Mapr,apache Drill Project founder, has ...
