Spark SQL Query

I am planning to take th exam next week. Do I require Spark SQL fro CC175 Certification? It says 

  • Write a query that produces ranked or sorted data using Spark-By query do you mean SQL query or query in Scala/Python?

Thanks!

Yes.  Both Spark and Hive are tools that can be used in the exam.  Transforming data, including sorting, is a skill that we recommend you understand.  So you should understand the different combinations.

 

The clusters are running CDH5.3.2 which do not support Spark SQL.
