use Pig and Spark SQL to solve the analytic problems for a set of linked tables. Now we have three data files with the following schema: customer(cid, name, age, city, sex), book(isbn, name), and purchase(year, cid, isbn, seller, price), where [url removed, login to view] is the foreign key to [url removed, login to view] and [url removed, login to view] is the foreign key to book.isbn. The fields in the dataset are separated by "\t". You should assign the schema, i.e., field names and and types, to the fields when you load the data.
Hi, I can do this assignment with Pig Latin and PySpark. My bid is an estimate and may change when more details are available about the project. Thanks!
