Big Data Analysis with Spark

Introduction

This repo demonstrates common big data analytics algorithms in python. The examples refer to the problems in Stanford's CS246 course.
Some codes require Apache Spark API to leverage MapReduce style of workload parallelism.

Requirements

  • Python 2
  • Apache Spark 2.4
  • NumPy
  • Pandas

Algorithms

No Description Spark
1 Friend recommendation by mining social-network graphs ✔️
