Zhu Zhu updated FLINK-14363:
----------------------------
Description:
DefaultScheduler currently will cancel latest execution of a vertex when the
vertex version is outdated. This may lead to undesirable failover of a healthy
vertex.
I'd propose to remove the vertex cancel process in
{{DefaultScheduler#stopDeployment}} because the cancellation is not not needed
here, since the version of a scheduled vertex is only outdated after the vertex
is canceled by others.
