Requirements

no upfront installation/agents on remote/slave machines - ssh should be enough
application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
configuration templating
environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
deployment process run from Jenkins

	// keepDoingSomething will keep trying to doSomething() until either
	// we get a result from doSomething() or the timeout expires
	func keepDoingSomething() (bool, error) {
	timeout := time.After(5 * time.Second)
	tick := time.Tick(500 * time.Millisecond)
	// Keep trying until we're timed out or got a result or got an error
	for {
	select {
	// Got a timeout! fail with a timeout error
	case <-timeout:

	package main

	import (
	"fmt"
	"time"
	)
