Test your knowledge

Before moving on to the next chapter, test your knowledge with the following questions:

1. Assume your data science team is using EMR notebooks for their interactive development and they are primarily using Python 3 for machine learning model development. When they started executing the Python code, they found some of their scripts are not getting executed; they get an error stating that the Python module does not exist. How would you make the additional Python modules available in the EMR notebook so that your data science team can continue executing their scripts for machine learning model development?
2. Assume you have an S3 data lake on top of which you have created Hudi tables for ACID transactions and UPSERT. You are updating records as they change, which creates multiple versions of the records in the Hudi table. You have received a business requirement to find the value of a specific column at a specific time. How would you fulfill that requirement...
