Learning Cloud and Big Data concepts is essential for the modern software developer, systems administrator, and IT project manager. Acquiring a professional certification is a key differentiator in the competitive software industry, and proves ones expertise with these technologies. The Hadoop* Knowledge Tester for Developers app will help prepare you for the rigorous Hadoop Developer certification tests offered by the industry leaders.
With classes costing thousands of dollars, and certification tests costing hundreds more, learning Cloud technologies is a significant and intimidating undertaking. However, regular use of this app as part of your certification preparation will fortify your existing knowledge, while exposing subjects that you need to review more thoroughly.
This app has an interface that is easy to use, so you can start learning immediately. This app tests your knowledge all Hadoop developer concepts that you will need to know, from the general architecture of Hadoop, to the use of the Java MapReduce API and the workings of the distributed filesystem. Both Classic MapReduce and YARN questions are included. Other components of the Hadoop ecosystem are also tested, including Hive, Pig, Sqoop, and Oozie.
No two tests from this app will be the same, as each question is selected from a database of hundreds of questions, each with multiple answer permutations. A timer will simulate the environment of an actual test. After completing each test, you will have an opportunity to review the answers to build your knowledge. Those who have 4-inch iPhones will also receive study hints for each question during review. Additionally, a history of your test scores will be kept so you can see your improvement over time.
Our engineers will be constantly revising our knowledge base to provide you with the most relevant and accurate test content to help you succeed. Whether you are learning Hadoop to update your skills, preparing for a career change, studying for an interview, or trying to earn a promotion, using this app will help you succeed.
