Hortonworks is excited to announce that our first hands-on, performance based certification exam is now available! The HDP Certified Developer (HDPCD) exam is designed for Hadoop developers working with frameworks like PigHiveSqoop and Flume. This new approach to Hadoop certification is designed to allow individuals an opportunity to prove their Hadoop skills in a way that is recognized in the industry as meaningful and relevant to on-the-job performance.
