Hadoop Studio : A map-reduce development environment (IDE) based on Netbeans

Hadoop Studio is a map-reduce development environment (IDE) based on Netbeans. It makes it easy to create, understand, and debug map-reduce applications based on Hadoop, without requiring development-time access to a map-reduce cluster. The studio provides a real-time workflow view of a map-reduce job, which displays the individual inputs, outputs, and interactions between the phases of a map-reduce job. The workflow view of a job updates in real time with the developer's code changes. It then generates Java sources and compiles them into a binary jar file, which can be run on a normal Hadoop cluster.

• Operating Systems : Linux, Windows
• Implementation : Java, Netbeans, hadoop, mapreduce

Vaadin : A Web application framework for Rich Internet Applications (RIA)

Vaadin is a Web application framework for Rich Internet Applications (RIA). In contrast to Javascript libraries and browser-plugin based solutions it features a server-side architecture, which means that the majority of the logic runs on the servers. AJAX technology is used on the browser side to ensure a rich and interactive user experience. Vaadin is a big collection of UI components. There are server-side components like Button, Table, and Tree that you use to compose the application user interface. The components use events, listeners, and data binding to communicate with each other and the business logic. Vaadin is a robust architecture for rapid application development. The component-based architecture together with the data binding features help you to build applications that are easily modularized and refactored as needed.
