Apache Spark 3 for Data Engineering and Analytics with Python - Challenge XYZ Research Part 2

The video tutorial covers solving two questions related to project completion using data sets. The first question involves determining projects completed in the first year by subtracting data sets. The second question requires finding projects completed in the first two years using union transformation and subtraction. The tutorial concludes with a summary and encourages viewers to practice further.

What is the primary goal of the lesson introduced in the first section?

• To learn about data visualization techniques

• To answer questions about project completions

• To explore machine learning algorithms

• To understand database management

How do you determine the projects completed in the first year using sets?

• By dividing set A by set B

• By multiplying set A and set B

• By adding set A and set B

• By subtracting set B from set A

What is the purpose of creating a new RDD in the second section?

• To visualize the data in a graph

• To calculate the average project duration

• To store the results of the subtraction for first-year projects

• To merge data from different years

What transformation is used to combine data from the first two years?

• Difference

• Union

• Intersection

• Concatenation

After combining data from the first two years, what is the next step to find completed projects?

• Add data from the third year

• Subtract data from the third year

• Multiply data from the third year

• Divide data from the third year
