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 ...

Apache Hadoop and MapReduce attract a large number of large data analysis experts and business intelligence experts. However, a wide range of Hadoop decentralized file systems, or the ability to write or execute mapreduce in the Java language, requires truly rigorous software development techniques. Apache Hive will be the only solution. The Apache Software Foundation Engineering Hive's database component, is also based on the cloud Hadoop ecosystem, provides the context based query statement called Hive query statement. This set of ...

Apache Pig, a high-level query language for large-scale data processing, works with Hadoop to achieve a multiplier effect when processing large amounts of data, up to N times less than it is to write large-scale data processing programs in languages ​​such as Java and C ++ The same effect of the code is also small N times. Apache Pig provides a higher level of abstraction for processing large datasets, implementing a set of shell scripts for the mapreduce algorithm (framework) that handle SQL-like data-processing scripting languages ​​in Pig ...

Among them, the first one is similar to the one adopted by MapReduce 1.0, which implements fault tolerance and resource management internally. The latter two are the future development trends. Some fault tolerance and resource management are managed by a unified resource management system: http : //www.aliyun.com/zixun/aggregation/13383.html "> Spark runs on top of a common resource management system that shares a cluster resource with other computing frameworks such as MapReduce.

This year, big data has become a topic in many companies. While there is no standard definition to explain what "big Data" is, Hadoop has become the de facto standard for dealing with large data. Almost all large software providers, including IBM, Oracle, SAP, and even Microsoft, use Hadoop. However, when you have decided to use Hadoop to handle large data, the first problem is how to start and what product to choose. You have a variety of options to install a version of Hadoop and achieve large data processing ...

Big data may be the most hot word in the tech world and VC circles. It seems that internet companies, even traditional industry companies, that don't have much of a big data connection have no future. is a hot word, there must be a bubble. Under the bubble, some companies that are really creating and digging into big data values, especially startups, are not known. There are companies that may still be in stealth mode, and they are now busy finishing the final finishing touches that will make it possible to change the rules of the game. Many of these big data startups ' teams come from Google ...
