Flintrock: A faster, better spark-ec2

Motivation
Common developer problem:
Give me a working clusterDon't bother me too much with the detailsMake it quick
2 / 26
spark-ec2
Single-purpose command-line toolLaunch and manage Spark clusters on EC2

Common use cases:PrototypingSpark performance testing (spark-perf)
4 / 26
spark-ec2
Problems:Slow launch times: ~9 minutes to launch 2-node cluster
5 / 26
spark-ec2
Problems:Slow launch times: ~9 minutes to launch 2-node clusterPoor UX
e.g. Having to type this out over and over again...
./spark-ec2 launch my-cluster \ --identity-file ~/.ssh/identity.pem \ --key-pair my-key \ --instance-type m3.medium \ --region us-east-1

Internals difficult to refactorMuch time has already been spent trying to make spark-ec2faster:

spark-ec2 was created as a convenience side-toolNot originally intended to stand as its own project

Why a new tool?
Plenty of great options out there:DatabricksSpark on EMRApache Bigtop, Ubuntu Juju, Terraform, Ansible, etc.

It's fun (for me to build)

It's fun (for me to build)Perhaps you don't want a framework
You want a single-purpose tool
