Enabling ECS Server deployment for High Availability (Technical Preview)
Learn how to enable ECS Server deployment for High Availability by installing a Load Balancer and promoting the existing ECS Agents to ECS Server. By performing this procedure, you will be able to deploy HA on your existing ECS Server.
If you have a production quality ECS cluster, then Cloudera recommends you to use ECS Server High Availability. You can also consider having an ECS Server HA for any non-production ECS cluster that you expect to be available long-term.
If you have Cloudera Manager 7.5.4, then you must have an ECS cluster installed and configured with a single ECS Server.
- An odd number of server nodes that will run etcd, the Kubernetes API, and other control plane services. Cloudera recommends a minimum of three ECS Server nodes.
- Two or more agent nodes that are designated to run CDP data services.
- A software or hardware Load balancer using TCP mode (non-terminating https).
