Answer:

The last point i.e .starting from "It breaks......multiple computer " is the correct answer to the given question.

Explanation:

Hadoop distributes large data processing across a cluster of commodity servers and works on multiple machines concurrently. To process any data, the client shall submit the data and the program to Hadoop. HDFS keeps the information while MongoDB processes the data and Yarn separates the tasks.

Hadoop is an open-source software platform for data storage and running applications on heterogeneous computing clusters. It provides vast storage for any kind of data, enormous computing power, and the ability to manage virtually infinite simultaneous activities or employment.  

All the other lines are not related to Hadoop that' why they are incorrect options .

zloy xaker [14]

Answer:

def enterNewPassword():

 while True:

   password = input("Enter password: ")

   has_digit = False

   for i in password:

     if i.isdigit():

       has_digit = True

       break

   

   if not has_digit or (len(password) < 8 or len(password) > 15):

     if len(password) < 8 or len(password) > 15:

       print("The password length must be between 8 and 15!")

     if not has_digit:

       print("The password must include at least one digit!")

   else:

     return password

print(enterNewPassword())

Explanation:

*The code is in Python.

Create a function named enterNewPassword that takes no parameter

Create an indefinite while loop. Inside the loop, ask the user to enter the password. Initialize the has_digit as False, this will be used to check if password contains a digit or not. Create a for loop, that that iterates through the password, if one character is digit, set the has_digit as True and stop the loop (Use isdigit() to check if the character is digit or not).

After the for loop, check if has_digit is false or the length of the password is not between 8 and 15. If the length of the password is not between 8 and 15, print the error. If has_digit is false, again print the error.

Otherwise, password met the requirements and return the password

Call the enterNewPassword() function and print the result

"in program arrays12.java a swap method is called. does the swap method exchange parameter values x and y?"
horrorfan [7]
<h2>Yes the swap method exchange parameter values if passed by reference or the value gets changed inside the function.</h2>

Explanation:

Since the program is not given, I will try to guide you about the mode of parameters.

The meaning of swap is interchanging the values. It can be done by using temporary variable or without using it (if the values are integers).

While passing the parameters, there are two ways, call by value/pass by value and call by reference/ pass by reference.

If call by value, then the value gets swapped only inside the function and will not reflected in the calling portion. Call by reference is other way round.

You want to create a directory called ~/Documents/papers, but you’re not sure that the ~/Documents directory exists. What comman
SCORPION-xisa [38]

Answer: e) mkdir -p ~/Documents/papers

Explanation:

As the question says we want to create a directory called ~/Documents/papers, but we are not sure whether it exist or not so we would type the command for making directory starting with mkdir.

Here mkdir means make directory. Followed by mkdir we will use -p. Here p is used to create all the directories for getting us the directory we want and its advantage is that it would ignore all the errors if the directory already exist.

Followed by the name of the directory that we want to create.

So the desired answer for the given condition would be mkdir -p ~/Documents/papers
