Cloudera offers enterprise and express versions of its Cloudera Distribution including Apache Hadoop. Cloudera’s view of the importance of qualified big data talent shines through the elements of its certification. It includes the following:
Cloudera Certified Specialist in Apache HBase (CCSHB) – HBase is a Java-based, non-relational distributed database and is modelled after Google’s BigTable environment. The certification is for IT professionals who work in this data platform.
According to TomsITpro, Cloudera was listed as one of the top Big Data certification providers and Hadoop as one of the top four Big Data platforms in use today. In case you need more reasons, here’s why you should go for Cloudera certifications:
Where can I take Cloudera certification exams?
Anywhere. All you need is a computer, a webcam, Chrome or Chromium browser, and an internet connection.
How do I register and schedule my Cloudera exam?
Once you complete your registration form on university.cloudera.com, you will receive an email with instructions to create an account at examslocal.com. Use the same email address you used to register with Cloudera. After creating an account, log in on examslocal.com, navigate to “Schedule an Exam”, and then enter “Cloudera” in the search field. Select the exam you want to schedule and follow the instructions to schedule your exam.
Can I reschedule or cancel an exam reservation?
In case you need to cancel or reschedule the exam, you need to sign in to https://www.examslocal.com. Click on ‘My Exams’ and proceed to your scheduled exam and use the cancellation or reschedule option available there. You must contact Innovative Exams at least 24 hours prior to your scheduled appointment as rescheduling or cancelling less than 24 hours prior to your appointment results in a forfeiture of your exam fees.
When can I retake the exam?
Candidates who did not succeed in the exam must wait for 30 calendar days, beginning the day after the unsuccessful attempt, before they can retake the same exam. You can take the examination as many times as you want until you pass. However, you must pay for each attempt.
Does the certification expire?
Yes! CCDH and CCAH certifications are aligned to a specific release of CDH (Cloudera’s Distribution, including Apache Hadoop) and remains valid for that version. Because the Apache Hadoop ecosystem is dynamic, it is recommended to keep the certifications updated.
Can I take the test again to improve my score?
Retakes are not allowed after the successful completion of the exam. A test result found to be in violation of the retake policy will not be processed, which will result in no credit awarded for the test taken. Repeat violators will be banned from participation in the Cloudera Certification Program.
