Samza on Azure

Setup a YARN cluster on Azure

This guide is to setup a YARN cluster with 1 RM (no HA) and multiple NM hosts.

1. Login to your account on http://portal.azure.com/
2. Start cloudshell (If needed, setup a new Storage Account and File Share)

git clone https://github.com/abhishekshivanna/samza-azure.git
cd azure-hacks/samza-terraform
terrform init

Note: this deployment assumes that a Resource Group and Network Security Group already exists.

Create a file called variables.tfvars and add the following contents

prefix = "<some-prefix-to-name-resources>"
resource_group_name = "<existing-resource-group-name>"
subscription_id = "<subscritpion-id>"
username = "<admin-username>"
password = "<admin-password>"
network_security_group_name = "<existing-network-sec-group-name>"
location = "westus2"
samza_vm_size = "Standard_D16s_v3"
vm_size = "Standard_D8s_v3"
yarn_nodemanager_resource_memory_mb = "49,152"

Take a look at the main.tf file under the samza-terraform directory. Keep only the "modules" that you want deployed as part of this run.

eg: if you don't want to deploy a Kafka cluster comment the module sections for zookeeper and kafka in main.tf

Deploy

terraform plan -var-file=variables.tfvars

Make sure that plan looks correct - its creating the appropriate resources. If you think the resources being created looks correct - run the following command

terraform deploy -var-file=variables.tfvars

Undeploy/Cleanup resources

terraform plan -destroy -var-file=variables.tfvars

Make sure everything being destoryed belongs to your deployment above. Then run the following command

terraform apply -var-file=variables.tfvars
