What You'll Need

For this tutorial, ensure you have:

  • Access to an HPE Ezmeral Unified Analytics (EzUA) cluster.

Procedure

To complete the tutorial follow the steps below:

  1. Login to your EzUA cluster, using your credentials.
  2. Create a new Notebook server using the jupyter-data-science image. Request at least 4Gi of memory for the Notebook server.
  3. Connect to the Notebook server, launch a new terminal window, and clone the repository locally.
  4. Navigate to the tutorial's directory (ezua-tutorials/tutorials/superset).
  5. Launch the Notebook files in order. Each Notebook file contains instructions on how to proceed.

How it Works

This tutorial provides step-by-step instructions on integrating external data sources with HPE EzUA. By accessing these datasets, you'll learn how to execute queries on tables within them using EzPresto, HPE's specialized version of the open-source distributed SQL query engine renowned for its rapid and scalable data querying and analysis capabilities. The outcomes of these queries will be illustrated through Charts within Views crafted in Apache Superset, an open-source platform for data visualization and exploration.
