You must know all about the Exam format if you are about to sit for the Spark and Hadoop Developer Certification Exam. The exam is remote-proctored, hands-on, and based on Cloudera technologies. During the exam, you'll be given your CDH6 cluster that is pre-loaded with Spark 2.4. During the exam, you may not use any websites or external packages.

Scala

The Scala and Spark and Hadoop Developer Certification (CCA) exam is a hands-on exam that tests your skills using Spark and Scala. It is also an excellent opportunity to show your coding skills. The CCA exam requires candidates to solve several scenarios using Spark and Scala, as well as Impala and Hive tools. The test templates provide the skeleton for a solution, and the candidate needs to fill in the blanks with functional code.

The Spark exam includes eight to twelve scenario-based questions and a 120-minute time limit. It would be best if you allowed yourself 10 to 13 minutes to complete each problem. In addition, the exam requires you to use a VM, which means you won't have the help of an IDE. However, there is a text editor that you can use to code and execute programs. Alternatively, you can use a spark-shell, which allows you to write code and run it while it runs. This allows you to debug the code while it is running, and you can reuse it later.
