Preface Having been in contact with Hadoop for two years, I encountered a lot of problems during that time, including both classic NameNode and JobTracker memory overflow problems, as well as HDFS small file storage issues, both task scheduling and MapReduce performance issues. Some problems are Hadoop's own shortcomings (short board), while others are not used properly. In the process of solving the problem, sometimes need to turn the source code, and sometimes to colleagues, friends, encounter ...

Within less than two months of Citrix turning its cloudstack into an Open-source Apache project, cloud providers are beginning to support this open source model. This week, for example, Zenoss company, which produces software that helps companies monitor and control data center functionality, adds Cloudstack support to its products. Floyd Strimling, head of cloud technology at Zenoss Company, said the company had started supporting cloudstack based on customer feedback. "We see a lot of final use ...

In Serengeti, there are two most important and most critical functions: one is virtual machine management and the other is cluster software installation and configuration management. The virtual machine management is to create and manage the required virtual machines for a Hadoop cluster in vCenter. Cluster software installation and configuration management is to install Hadoop related components (including Zookeeper, Hadoop, Hive, Pig, etc.) on the installed virtual machine of the operating system, and update the configuration files like Namenode / Jobtracker / Zookeeper node ...

Starting and stopping virtual machines is a routine use of cloud computing resources. There are two basic options for deploying virtual machines in the cloud: Customers can copy a pre-configured virtual machine image (also known as the final version), or they can assemble a custom virtual machine image as required. To enable a virtual machine, first select a machine image from the Cloud directory. When you are deploying a >apache with http://www.aliyun.com/zixun/aggregation/14417.html "We ...

"Editor's note" in the famous tweet debate: MicroServices vs. Monolithic, we shared the debate on the microservices of Netflix, Thougtworks and Etsy engineers. After watching the whole debate, perhaps a large majority of people will agree with the service-oriented architecture. In fact, however, MicroServices's implementation is not simple. So how do you build an efficient service-oriented architecture? Here we might as well look to mixrad ...

Cloud computing is one of the areas where open source software has become increasingly popular within companies as the economy continues to slide, and cloud computing itself can provide flexibility and lower costs for companies. The deployment of cloud computing can save a lot of money for the company and release it from the time-consuming vendor lock-in model, while providing a flexible connection to private applications. 　　Here are 11 open source cloud computing resources, including applications, services, educational resources, support options, general profit projects, and more. Eucal ...

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 ...
