Components in play

As a reminder, here are the components in play to run an application:

The cluster:

Spark Master: coordinates the resources
Spark Workers: offer resources to run the applications


The application:
	pragma solidity 0.4.25;

	contract SimpleStorage {
	uint numChicken;

	function set(uint x) public {
	numChicken = x;
	}

	function get() public constant returns (uint) {
