Skills Gained
Through instructor-led discussion and interactive, hands-on exercises, participants will learn Apache Spark and how it integrates with the entire Hadoop ecosystem, learning:
- How data is distributed, stored, and processed in a Hadoop cluster
- How to use Sqoop and Flume to ingest data
- How to process distributed data with Apache Spark
- How to model structured data as tables in Impala and Hive
- How to choose the best data storage format for different data usage patterns
- Best practices for data storage
Prerequisites
This course is designed for developers and engineers who have programming experience. Apache Spark examples and hands-on exercises are presented in Scala and Python, so the ability to program in one of those languages is required. Basic familiarity with the Linux command line is assumed. Basic knowledge of SQL is helpful. Prior knowledge of Hadoop is not required.
Course Details
This four-day hands-on training course delivers the key concepts and expertise participants need to ingest and process data on a Hadoop cluster using the most up-to-date tools and techniques. Employing Hadoop ecosystem projects such as Spark, Hive, Flume, Sqoop, and Impala, this training course is the best preparation for the real-world challenges faced by Hadoop developers. Participants learn to identify which tool is the right one to use in a given situation, and will gain hands-on experience in developing using those tools
CCA Spark & Hadoop Developer
This course is an excellent place to start for people working towards the CCA Spark & Hadoop Developer certification. Although further study is required before passing the exam, this course covers many of the subjects tested in the CCA Spark & Hadoop Developer exam. After successfully completing this course, we recommend that participants attend Cloudera’s Designing and Building Big Data Applications course, which builds on the foundations taught here.

Very clean, great cafeteria and well sorted, very kind staff. The bathrooms have to be expanded as they might get crowded sometimes
Concise and good to follow along. Although it is a lot to take in under a short period of time.
I thought the course was informative and the tools to go over the material were very nice.
ExitCertified was a great. They gave me all the materials and information I needed ahead of time to prepare for the course.
Class was easy to sign up for and ExitCertified provided very good communication
