Apache Spark for Data Science Cookbook

By: Padma Priya Chitturi

Overview of this book

Spark has emerged as the most promising big data analytics engine for data science professionals. The true power and value of Apache Spark lies in its ability to execute data science tasks with speed and accuracy. Spark’s selling point is that it combines ETL, batch analytics, real-time stream analysis, machine learning, graph processing, and visualizations. It lets you tackle the complexities that come with raw unstructured data sets with ease. This guide will get you comfortable and confident performing data science tasks with Spark. You will learn about implementations including distributed deep learning, numerical computing, and scalable machine learning. You will be shown effective solutions to problematic concepts in data science using Spark’s data science libraries such as MLLib, Pandas, NumPy, SciPy, and more. These simple and efficient recipes will show you how to implement algorithms and optimize your work.

Preface

Customizing Zeppelin's server and websocket port


Zeppelin runs on port 8080 by default, and it has a websocket port enabled at the +1 port 8081 by default. We can customize the port by copying conf/zeppelin-site.xml.template to conf/zeppelin-site.xml and changing the ports and various other properties, if necessary. Since the Spark standalone cluster master web UI also runs on 8080, when we are running Zeppelin on the same machine as the Spark master, we have to change the ports to avoid conflicts:

For now, let's change the port to 8180 by editing the configuration file shown in the following image. In order for this to take effect, let's restart Zeppelin using bin/zeppelin-daemon restart. Now Zeppelin can be viewed on the web browser by visiting the site http://localhost:8180 and the web browser looks like the following screenshot:
