I have read the link provided by you and found that the CCA Exam will contains 10 performance based questions.
But My query is that will the exam questions be full fledged programs that needs to be written in Editors(Eclipse) and compiled using build tools(SBT/Maven) or will they be missing pieces of Code within those programs that needs to be filled in with required code.
I am quite interested in writing CCA Spark and Hadoop exam. The current version is using Spark 1.6. However i wish to write the exam using Spark 2.x version. Is this possible to write exam using Spark 2.x API?
