Feelings and Experiences of CCD-333 Exam - Cloudera Certified Developer for Apache Hadoop (CCDH)

In October this year, I took a Cloudera Certified Developer for Apache Hadoop exam, which number is CCD-333. I successfully passed the exam, and looking back upon, all the efforts paid had value. This is a new exam and there is few materials in the internet talking about it, now I want to write something to share my feelings and experiences, which may help people who are preparing for the exam.


Part 1: Exam Preparation - Learning
1. Hadoop The Definite Guide 3rd


This is the book you must read before the exam, which explain very well and in details of Hadoop. I took a three days training by Cloudera certified trainer, but that class is an overview level training and is not very detailed. After the exam, I found the many questions examed are in the Definite Guide book rather than the training.
And very important, it's better that you read very carefully of Chapter 2 to 8 of this book, and maybe add chapter 9 and 10. I read them twice. But for chapter 11 to 16 which talks about the ecosystem of Hadoop (HBase, Hive, Pig etc.) , you don't need to read them if only for preparing the exam.

Part 2: The Exam CCD-333
The CCD-333 exam is 90 minutes with 60 questions, and the requirement is to score 67% or above. The exam tests many areas, the section scores below listing them precisely:

I feel that it exams a lot in the Input and Outpout of MapReduce, you need to understand the flow and details of MapReduce, and in the exam itself, I feel that time is sufficient to finish the exam.

Part 3: The certification

I wish this article is helpful for those who are preparing for this exam. All the best!

Do you need to attend an hadoop class in order to be awarded the certificate?

Sai said...

Hi Cheick Sall,
Thanks for asking.
No, a class room training is not required. You have a certification once you passed the exam.

It was hard for me even to think about CCA175 exam as it is a very difficult IT certification. I was not having any background knowledge but I am thankful to
CCA175 dumps for being so comprehensible. I memorized all the questions and answers in CCA175 dumps.

If you ask me for a suggestion about your preparation for CCA Spark and Hadoop Developer Exam then I will definitely suggest you to take CCA Spark and Hadoop Developer CCA175 Dumps for definite success. I was suggested in the same way and now I am happy for my trust. The questions and answers were to the point and brief according to the exam requirements. I will always prefer Dumps4download for all the exams I am going to appear in future.
