HW assignments from the 2018 Spring semester. The final project folder includes a write up as well as all the code. The JSON for HW5 is an exported Zeppelin notebook. The .scala file has the code for that notebook and a formatted version of the notebook can be found here: https://www.zepl.com/viewer/github/troyyyang/Large-Scale-Information-Storage-and-Retrieval-DS4300-HW/master/yangt_hw5.json.
