Hello Community, Yang, I noticed a conflict in the document for per-job mode support for Kubernetes. In the doc here [1], it mentions in a Flink Job Cluster, the available cluster manager (like YARN or Kubernetes) is used to spin up a cluster for each submitted job and this cluster is available to that job only. It implies per job mode is supported in Kubernetes. However, in the docs [2] and [3], it clearly points out per-job mode is not supported in Kubernetes. This is a conflict statement and is kind of misleading. If needed, I can create an MR to delete the statement in [1] for Kubernetes.. It is a small fix.
I also noticed another thing in the video [4] at 25:08. Yang, you are executing a command with -e kubernetes-per-job flag. I tried and found such command is not supported in Flink distribution at all. I noticed the version you are using
is 1.11-snapshot during the demo. Are you modifying the source code and generated an internal version of Flink….?

Hi Fuyao, Currently, Flink only supports perjob mode for Yarn. The standalone job cluster has been replaced with standalone application mode after FLIP-85[1]. Both standalone Flink on K8s and native K8s integration do not support per-job mode. In your attached video, it is a PoC implementation for presentation. We have introduced the Kubernetes application mode in release 1.11 and agree to not have a per-job cluster support. The only reason is that it is not very convenient to ship the job graphs, user jars, artifacts in Kubernetes environment. Best, Yang Fuyao Li <[hidden email]> 于2021年4月13日周二 上午8:10写道:
