Sub-Task 2 In this homework, you are expected to familiarize yourself with Python's higher order functions, in particular, map(), filter() and reduce(). For example, the program could be run as: python show_bus_locations.py xxxx-xxxx-xxxx-xxxx-xxxx B52. Please write a Spark application that takes the above file yellow_tripdata_2011-05.csv on HDFS as its input and produce the top 3 origin neighborhoods that delivered passengers to each of the five borough based on the number of trips served. Data scientists and engineers increasingly have access to a powerful and broad range of systems they use to conduct big data analysis and machine learning at scale: from databases, large-scale analytics to … For buses that do not have this information, please output “N/A” in the stop information fields. You are also provided with the spatial boundaries for the NYC boroughs and neighborhoods. Your program will have to output the following to the console, which consists of the bus name, the number of vehicles and their current position: ######Task 2 Intended for non-majors. The data set must be loaded into an RDD, where all your manipulations must be applied on. For sanity check, please also include your output (the two 3 words and their counts) in your submission. You can use the citibike.csv data file that we have on Blackboard for testing, but we will evaluate your code on a much larger input to ensure its streaming capability. You are provided a list of service status updates scraped from an MTA information website. You will learn about schema design, data modeling, query languages, building database applications, transactions, and many other topics. You are tasked to write a chain of map(), filter(), and/or reduce() to convert the status variable into a list like below: Please note that you may only use higher order functions without access to global variables. Your expression should contain only map(), filter() and/or reduce() and your custom function definitions. You are asked to compute the average SAT Math score of all high schools with 500 students or more, for each borough of the city. Sub-Task 1 The final hand-in should be a single Python file, named show_bus_locations.py that takes exactly 2 arguments in the following format: CSE230 HW1. West Village, Williamsburg, Flushing, etc.) In this course, we will introduce the basics of modern data management. Both data sets must be loaded into RDDs, where all your manipulations must be applied on, though you are free to transform these RDDs into Spark’s DataFrame or SQL Context. The midterm exam will be held in class on Wednesday, Oct. 31st, covering materials from units 1, 2 (lectures and sections up to October 18). The final hand-in should be a single Python file, named get_bus_info.py that takes exactly 3 arguments in the following format: python get_bus_info.py xxxx-xxxx-xxxx-xxxx-xxxx M7 M7.csv. For example, an answer could be that Upper East Side, Midtown West, and Laguardia Airport are the top 3 origin neighborhood for trips ending up in Manhattan. The final result is expected to be a single number as the median trip time in minutes. CSE384: Systems Programming Course information. uw cse414. However, we’ll be using NYC open data sets instead of web clicks, in particular: the SAT Results and the NYC High School Directory data sets.
