The text files orders.txt and details.txt contain information about the orders submitted by the customers and about the details of each order, i.e. the items included in each order. Each file consists of a line with a header and a number of lines with data. The sample rows included in the files are the following. orders.txt order, number, customer-number 0001,1234 0002,1234 0003, 7890 details.txt order-number,line-number, item-name, quantity 0001,01,bolt, 25 0001,02, screw, 20 0002,01,bolt,100 0002,02, nut,300 0003,01, trolley,1 The headers of the files have been removed and the files have been loaded to HDFS to a location /bigdata/orders. (1) Load the contents of a file details.txt located in HDFS into a Resilient Distributed Dataset (RDD) and use RDD to find the total quantity per each item. (2) Load the contents of a file details.txt located in HDFS into a Dataset and use the Dataset to find the total quantity per each item. (3) Load the contents of a file details.txt located in HDFS into a DataFrame and use SQL to find the total quantity per each item.

Create a datafile that contains the first name, last name, gender, age, height, smoking preference, eye color and phone number. Add a variety of records to the file. A sample file looks like: Write a program that opens the file and reads the records one by one. The program will skip any records where the gender preference is not a match. Of those records that match the gender preference, check to see if the age and height are between the maximum and minum preferences. Then check to see if the smoking preference and eye color are also a match. If at least 3 of the remaining fields match, consider the record a partial match, and print it in the report. If all 4 of the remaining fields match, the record is a perfect match and print it in the report with an asterisk next to it. At the end of the program, close the file and report how many total records there were of the specified gender, how many were a partial match, and how many were a perfect match.
