THE HDPCD EXAM
Our certifications are exclusively hands-on, performance-based exams that require you to complete a set of tasks. By performing tasks on an actual Hadoop cluster instead of just guessing at multiple-choice questions, Hortonworks Certified Professionals have proven competency and Big Data expertise. The HDP Certified Developer (HDPCD) exam has three main categories of tasks that involve:
The
exam is based on the Hortonworks Data Platform 2.4 installed and managed with
Ambari 2.2, which includes Pig 0.15.0, Hive 1.2.1, Sqoop 1.4.6, and Flume 1.5.2.
Each candidate will be given access to an HDP 2.4 cluster along with a list of
tasks to be performed on that cluster.
To
be fully prepared for the HDP Certified Developer exam, candidates should be
able to complete all
of the exam objectives.
