The road to computer science is littered with things that will become "the next big thing". Although many niche languages do find some place in scripts or specific applications, C (and its derivatives) and Java languages are hard to replace. But Red Hat's Ceylon seems to be an interesting combination of some language features, using the well-known C-style syntax, but it also provides object-oriented and some useful functional support in addition to simplicity. Take a look at Ceylon and see this future VM ...

The development of spark for a platform with considerable technical threshold and complexity, spark from the birth to the formal version of the maturity, the experience of such a short period of time, let people feel surprised. Spark was born in Amplab, Berkeley, in 2009, at the beginning of a research project at the University of Berkeley. 　　It was officially open source in 2010, and in 2013 became the Aparch Fund project, and in 2014 became the Aparch Fund's top project, the process less than five years time. Since spark from the University of Berkeley, make it ...

Hadoop is a large data distributed system infrastructure developed by the Apache Foundation, the earliest version of which was the 2003 original Yahoo! Doug cutting is based on Google's published academic paper. Users can easily develop and run applications that process massive amounts of data in Hadoop without knowing the underlying details of the distribution. The features of low cost, high reliability, high scalability, high efficiency and high fault tolerance make Hadoop the most popular large data analysis system, yet its HDFs and mapred ...

This time, we share the 13 most commonly used open source tools in the Hadoop ecosystem, including resource scheduling, stream computing, and various business-oriented scenarios. First, we look at resource management.

In the past, assembly code written by developers was lightweight and fast. If you are lucky, they can hire someone to help you finish typing the code if you have a good budget. If you're in a bad mood, you can only do complex input work on your own. Now, developers work with team members on different continents, who use languages ​​in different character sets, and worse, some team members may use different versions of the compiler. Some code is new, some libraries are created from many years ago, the source code has been ...

Today, more and more PAAs (platform service) providers, in the field of cloud computing has launched a fierce competition. Cloud computing works well with the development mechanism for deploying applications.     IAAS providers provide basic computing resources, SaaS providers provide online applications such as online CRM, and PAAs offerings provide developers with a one-stop service that allows our applications to start and run quickly without paying attention to some infrastructure issues. As a service provided on the PAAs platform ...

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 ...

Spark conversion (transform) and Action (action) list. The following func, most of the time, to make logic clearer, we recommend using anonymous functions! (lambda) "" "Ps:java and Python APIs are the same, names and parameters are unchanged." Transform meaning Map (func) Each INPUT element is exported after a Func function conversion and output an element filter (func) returns the value returned after the Func function evaluates to The input element of true is composed of ...
