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.

This is the 6th article I wrote about building a "Nginx + PHP (FastCGI)" Web server. This series of articles as the earliest detailed introduction Nginx + PHP installation, configuration, use of one of the information to promote Nginx in the domestic development has produced a positive role. The 6th article mainly introduces the new smooth restart method of Nginx 0.8.x, and upgrades PHP to 5.2.14, and fixes the pear problem. Another MySQL 5.1.x upgrade to the 5.5.x series, configuration files ...

1. The foreword Scheduler is the core component of Mesos, which is mainly responsible for allocating resources on each slave to each framework, and the common scheduling mechanism is Fifo,fair scheduler,capacity Scheduler,quincy,condor. Mesos in order to support the multi-framework access, the two-layer scheduling mechanism is adopted, first, the resource is allocated to the framework by the allocator in Mesos, then the framework itself ...

"IT168" with the increasing demand for large data solutions, Apache Hadoop has quickly become one of the preferred platforms for storing and processing massive, structured, and unstructured data. Businesses need to deploy this open-source framework on a small number of intel® xeon® processor-based servers to quickly start large data analysis with lower costs. The Apache Hadoop cluster can then be scaled up to hundreds of or even thousands of nodes to shorten the query response time of petabytes to the second.

Now many industries or services are under the banner of cloud computing, but not all of it is cloud computing, quweicunzhen see cloud computing, is to grasp the real core cloud computing, cloud computing has two important aspects, integral, neglected, one is centralized computing, one is distributed computing, Cloud computing is a historical product that blends both in a specific way. Ignoring any point will have serious one-sidedness. Now a lot of "pseudo cloud computing" is not necessarily said to be completely detached things, but to the cloud of a side, or some of the history of a local source, exaggerated to the cloud meter ...

Before the formal introduction, it is necessary to first understand the kubernetes of several core concepts and their assumed functions. The following is the kubernetes architectural design diagram: 1. Pods in the kubernetes system, the smallest particle of dispatch is not a simple container, but an abstraction into a pod,pod is a minimal deployment unit that can be created, destroyed, dispatched, and managed. 　　such as a container or a group of containers. 2. Replication controllers ...

The operating language of the data is SQL, so many tools are developed with the goal of being able to use SQL on Hadoop. Some of these tools are simply packaged on top of the MapReduce, while others implement a complete data warehouse on top of the HDFs, while others are somewhere between the two. There are a lot of such tools, Matthew Rathbone, a software development engineer from Shoutlet, recently published an article outlining some common tools and scenarios for each tool and not ...
