Flink: How to configure Flink such that the Taskmanagers auto restart after a failure?

Question

如何配置 Flink 使任务管理器在失败后自动重启？

Answer 1

On yarn and kubernetes Flink has a native resource manager ( YarnResourceManager and KubernetesResourceManager ) that will arrange for the requested number of slots to be available. In other environments you'll need to use cluster-framework-specific mechanisms to take care of this yourself.

Note that for k8s, only session clusters are supported by this new, more active mode implemented by KubernetesResourceManager . Job clusters still need to be managed in the old fashioned way, as described in the docs .

And then there are managed Flink environments where these details are taken care of for you -- eg, Ververica Platform or Kinesis Data Analytics.
