As part of this accelerated course, you'll receive the following exam voucher:

• Cloudera Certified Developer for Apache Hadoop (CCD-410)

The exam consists of 55 questions and must be completed within 90 minutes. You must have a passing score of at least 70% to get your certification.

This course will cover content and practical tests to cover preparation to the exam. Firebrand cannot deliver the exam at our centre. Delegates will be provided with an exam voucher to take the exam.

Included:

• Official Cloudera courseware

This course is best suited to developers and engineers with programming experience. Knowledge of Java is strongly recommended and is required to complete the hands-on exercises. Prior knowledge of Apache Hadoop is not required.

Seven reasons why you should sit your course with Firebrand Training

1. Two options of training. Choose between residential classroom-based, or online courses
2. You'll be certified fast. With us, you’ll be trained in record time
3. Our course is all-inclusive. A one-off fee covers all course materials, exams**, accommodation* and meals*. No hidden extras.
4. Pass the first time or train again for free. This is our guarantee. We’re confident you’ll pass your course the first time. But if not, come back within a year and only pay for accommodation, exams and incidental costs
5. You’ll learn more. A day with a traditional training provider generally runs from 9 am – 5 pm, with a nice long break for lunch. With Firebrand Training you’ll get at least 12 hours/day of quality learning time, with your instructor
6. You’ll learn faster. Chances are, you’ll have a different learning style to those around you. We combine visual, auditory and tactile styles to deliver the material in a way that ensures you will learn faster and more easily
7. You’ll be studying with the best. We’ve been named in the Training Industry’s “Top 20 IT Training Companies of the Year” every year since 2010. As well as winning many more awards, we’ve trained and certified over 135,000 professionals

• For residential training only. Doesn't apply for online courses
