This post is part of my preparation series for the Cloudera CCA175 exam, “Certified Spark and Hadoop Developer”. It is intentionally concise, to serve me as a cheat sheet.
You need familiarity with Python as well as Scala for the Cloudera exam. I have never coded in Scala before, so I am taking this course and preparing a brief Scala summary in this post.
spark-shell is very helpful in the exam, and you don’t need to compile any .jar files.
