Example projects for 'BigInsights for Apache Hadoop' on IBM Bluemix

This repository contains example projects for BigInsights. Following the steps below on your client machine, it should take you less than 5 minutes to run any of the example projects against a BigInsights cluster. The projects are tested on BigInsights on IBM Bluemix but they should also work for BigInsights on-premise. Note that all of the examples are community supported.

The core idea is that you can run an example project to see it working against your BigInsights cluster. You can then copy the project and adapt it to add your own custom logic. Think of the example projects as working blueprints.
