CSC4760 Assignment 5 Solved

1. ( (Counting Tweets)

Input Datasets:

Tweets (tweets.json):

City and State lookup table (cityStateMap.json):

Problem and Output Data:

We want to count the number of tweets published in each state. The following table shows the desired results.

Implementation:

Design and implement a PySpark program to solve the problem. We did not provide any template python file this time. You may want to create one python file from scratch.

You are required to use Spark Dataframe to implement this function.

Report:

Please write a report illustrating your experiments. You need to explain your basic idea about how to count tweets in each state. You may add comments to the source code such that the source code can be read and understood by the graders.

In the report, you should include the answers to the following questions. 1) Explanation of the source code
2) Experimental Results

2.1) Screenshots of the output. Since we plan to use Dataframe in Spark, it is easy to type in “DF.show()” to visualize the table in the terminal. Please do so and take a screenshot of the output in the terminal. The screenshot “output.PNG” of the output in my VM is given. You can use it to verify your outputs.

2.2) Explain your results. Does your implementation give the right answer?
