FuyaoLi2017 opened a new pull request #15602:
URL: https://github.com/apache/flink/pull/15602
## What is the purpose of the change
I noticed a conflict in the document statement 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.
To avoid the misunderstanding, I think we should fix the statement in the
Flink Architecture page and add an extra hint note here. I had a discussion
with @wangyang0918 on flink user mailing list earlier on this issue and he
agrees to patch such a change.
