DockerDoop is an extension of the Hortonworks University solution for running multi-node HDP clusters in a single VM using Docker. It simplifies HDP dev/test workloads such as those related to HA, Kerberos, failover scenarios, and multi-node demos. This is especially useful for blueprint testing, because a blank cluster can be destroyed and recreated in less than 1 minute.
3-6 node clusters can be run with only 6-8GB of RAM and multiple clusters can exist in the same VM. All HDP ports on all nodes are externally accessible (i.e. from the workstation).
