-----------------------------------
I test four scenarios
# Kubernetes
## Session Cluster
### Deploy a session cluster to the k8s
### Access the JobManager Web
### Check the master have the KubernetesLeaderElector log
### Submit a StateMachineExample.jar job
### Verify that there are some complete checkpoint
### Kill the jobmaster pod
### Verify that job could recovery from previous checkpoint
## Perjob Cluster
### Build a perjob image
registry.cn-beijing.aliyuncs.com/streamcompute/flink:k8s-ha-per-job
### Deploy Perjob cluster
### Access the JobManager Web
### Check the master have the KubernetesLeaderElector log
### Verify that there are some complete checkpoints
### Kill the pod
### Verify that job could recovery from previous checkpoint
# Native Kubernetes
## Session Cluster
### Start a native k8s session
### Access the JobManager web
### Check the KubernetesLeaderElector log
### Submit a StateMachineExample.jar job
### Verify that there are some complete checkpoints.
### Kill the pod
### Verify that job could recovery from previous checkpoint
## Start Application
### Start a flink application
### Access the JobManager web
### Check the KubernetesLeaderElector log
### Kill the pod
### Verify that job could recovery from previous checkpoint
---------------------------------------------------------------------------------
In general the new HA service is work. Most problems I found are about the log
and documentation.
