Hi, I have setup Filnk 1.9.1 on Kubernetes on AWS EKS with one job manager pod, 10 task manager pods, one pod per EC2 instance. Job runs fine. After a while, for some reason, one pod (task manager) crashed, then the pod restarted. After that, the job got into a bad state. All the parallelisms are showing different color (orange, purple) on the console. I had to basically stop the entire job. My question is should a task manager restart affect the entire cluster/job? Or should it join back gracefully?
Second question is regarding to auto scaling Flink cluster on kubernetes. If I add more nodes/pods (task manager containers) to the cluster, will a running Flink job redistribute load to the additional resources or I have to stop to a savepoint, and restart the job? Thanks and regards. Ivan
