Regarding Hortonworks Certification Tips
- You need to have hands experience on HDP2.4 sandbox it is mandatory to complete the certification.
- You need to have a handson knowledge in Pig,Hive,Sqoop and Flume before giving the final exam.
- Practice as much examples you can provided by hortonworks in training section.
- Once you are confident enough take 1 week and revise all the stuff what you have done till.
- Now take the practice exam provided by the Hortonworks guys on AmazonEC2 which costs you less than a dollar [i.e., 40 to 50 rs INR].
- Take the practice exam repeatedly and solve the practice questions.
Most probably you will get same type of questions with respect to topics given in practice exam.
