An Acquaintance with Hadoop

Regardless, there is no denying that this software does have a large number of fans!

Hadoop refers to an open-source framework. This software proves wonderfully useful for processing Big Data, as well as storing it. Hadoop bonds well with Java, the tremendously popular programming language. Therefore, it is easy to comprehend. The Apache 2 license covers Hadoop.

Acquiring Hadoop Certification

This certification will pave the pathway for you to become a successful Big Data engineer. For one thing, the training program delves deep into the methodologies and tools, which come into play for Big Data.

Regardless, you may not go back to the completed questions, once you return to your seat. Then again, you may not take extra time to complete the paper.

The practice test shows your strengths and weaknesses. It should help you brush up on your learning as you prepare for the actual certification exam. You may even draw upon your experiences as a working professional. You must get a high score, beyond 70% at least, if you wish to obtain Hadoop certification. Otherwise, the examiner will decide that you have failed. Of course, you may attempt the exam once again, albeit only after 30 days have gone past. You may take three retakes in total.
