- Some things can be similar and still have some differences. The Hadoop ecosystem is known to be the add-ons that make the Hadoop framework more better for some particular big data needs and tastes.
The Hadoop ecosystem is made up of the open source projects and commercial tools that are often optimized to act on different kinds of work especially to big data. It is very flexible
The differences is that cluster is simply a combination of a lot of computers that is set up to work together as one system but a Hadoop cluster is a cluster of computers that is used only at Hadoop. Hadoop clusters are set up to analyze and storing large amounts of unstructured data only in a distributed file systems.

</span>Adding a shadow behind the table will make the <span>data table to stand out on the screen and help bring the viewer’s attention.
Shades can be added also on text, tables, pictures inserted in the presentation and other object. </span>
Answer:
A)
This is an example of tight coupling since the class Working has to have an idea of how Person is implemented to complete its own implementation.
B)
Any change in the Person class would require a change in the working class too.
C)
CODE
class Person {
int personID, age;
String fName, middleName, lastName;
public int getAge() {
return age;
}
}
// end of Person class
class Working extends Person {
boolean isUnderEighteen() {
if (super.getAge() <18) {
System.out.println("The person is under age and cannot work");
return true;
}
else {
System.out.println("The person can legitimately work");
return false;
}
}
}

Answer:
A class is like a blueprint of object.
Explanation:
A class defines the kinds of data and the functionality their objects will have.
A class enables you to create your own custom types by grouping together variables of other types, methods and events.
In C#, we can create a class using the class keyword.
Here's a sample program:
using System;
namespace ConsoleApplication
{
public class Test
{
public static void Main()
{
Add a1 = new Add(70, 50);
a1.AddNumbers();
Console.ReadLine();
}
}
class Add
{
private int row;
private int column;
public Add(int r, int c)
{
row = r;
column = c;
}
public void AddNumbers()
{
Console.WriteLine(row+column);
}
}
}
output: 120
Explanation of the program:
I have created a class named Add. Within a class, row and column are two fields and AddNumbers() is a method. We also have constructor to initialize row and column.
In main method, If I need to invoke members of the class, I must create an instance of the class. We can create any number of instances using the single class.IN our program, a1 is the reference variable using which we can invoke members of the class. I invoked function in the class and passed arguments to the constructor while creating an instance.
Those values are assigned to method variables and it operated the addition. Thus the output is 120.
