Apache Spark 3 for Data Engineering and Analytics with Python - Challenge - Convert Fahrenheit to Centigrade

The video tutorial guides learners through a challenge of converting temperatures from Fahrenheit to Celsius using RDDS in PySpark. It begins with an introduction to the challenge, followed by a detailed solution using map and filter functions. The tutorial includes setting up a Spark session, preparing data, defining a conversion function, and applying transformations. The lesson concludes with a summary and a preview of the next exercise.

What is the primary task in the first challenge presented in the video?

• Find the maximum temperature

• Convert temperatures from Celsius to Fahrenheit

• Convert temperatures from Fahrenheit to Celsius and filter them

• Calculate the average temperature

Which tool is used to create a new notebook for the RDD challenge?

• PySpark

• RStudio

• Google Colab

• Jupyter Notebook

What is the first step in preparing the data for the RDD challenge?

• Write a function to convert temperatures

• Create a list of temperatures

• Initialize a Spark session

• Create a DataFrame

What is the purpose of the function defined in the solution implementation?

• To calculate the average temperature

• To sort the temperatures

• To convert temperatures from Fahrenheit to Celsius

• To filter temperatures above 13 degrees Celsius

Which PySpark function is used to apply the temperature conversion to all elements in the RDD?

• reduce

• filter

• map

• collect

What is the condition used to filter the temperatures in the RDD?

• Temperatures greater than or equal to 13 degrees Celsius

• Temperatures less than 13 degrees Celsius

• Temperatures equal to 13 degrees Celsius

• Temperatures greater than 15 degrees Celsius

What is the final step in the solution implementation?

• Filter the temperatures and print the results

• Print the original list of temperatures

• Convert the temperatures and print the results

• Save the results to a file
