### **4.1 Spark Pi**

Test the Spark installation by running the following compute intensive example, which calculates pi by “throwing darts” at a circle. The program generates points in the unit square ((0,0) to (1,1)) and counts how many points fall within the unit circle within the square. The result approximates pi.

Follow these steps to run the Spark Pi example:

 *     <ul>
 *       <li>Removes dependency {@code <version>} when it points to a project artifact</li>
 *       <li>Removes dependency {@code <groupId>} when it points to a project artifact</li>
 *       <li>Applies to main dependencies, profile dependencies, and plugin dependencies</li>

 * information among plugins, is this more like an extension point - do we need a sort of bus for
 * application data - do we need a dictionary for our applications like Apple does. We could easily
 * hook into this and this is the model we need to follow - how many of our REST services do not map
 * directory to a method in the application interface?
 *
 * - research extension points versus plugins
