21. (2 points) Create a class to represent rectangles. A rectangle is specified (as with drawing them in Processing) by the coordinates of its upper left corner, its width, and its height. Give your class just enough functionality to make it work with the program below. The display() method should simply draw the rectangle with no change in fill or stroke. Rectangle[] boxes = new Rectangle [100]; void setup() { size (400, 400); for (int i = 0; i < boxes.length; i++) { boxes[i] = new Rectangle((int) random (width), (int) random (height), (int) random (10,40), (int) random (5, 20)); void draw() { for (int i = 0; i < boxes.length; i++) { fill (random (255), random (255), random (255)); boxes[i].display();

Using Hadoop for historical sales data analysis 

Use this dataset to analyze various aspects of transaction 

1) Average unit_price by country for a given item type in a certain year

2) Total units_sold by year for a given country and a given item type

3) Find the max and min units_sold in any order for each year by country for a given item type. Use a custom partitioner class instead of default hash based.

4) What are the top 10 order id for a given year by the total_profit 

Please help in doing  above analysis working on a Hadoop system using map reduce code, written either in Java or Python.  Data preparation steps can be done as required before running a MapReduce job to answer  questions above. 

Dataset:

A publication company that markets both book and audiocassets versions of its works.
create a class called publication that stores the title (a string) and price (type float) of
publication. This class includes getdata() and showdata() member functions for input and output
data members. This class also includes a pure virtual member function “ISOversize()”. From this
class derive two classes: Book, which has a page count (type int) and Tape class which has a
playing time in minutes (type float). Each of these two derived classes should override the base
class member functions. Let’s say that a book with more than 500 pages, or a tape with a
playing time longer than 90 minutes, is considered oversize. You can access member functions
from main() and display the string “Oversize” for oversized books and tapes when you display
their data.
Write a main() program that creates an array of pointers to publication. In a loop, ask the user
for data about a particular book OR tape.
