> Reject/guard 'transfer leadership' to an SCM that is not ready to serve (no
> DN heartbeats / empty NodeManager view)
> -------------------------------------------------------------------------------------------------------------------

> Key: HDDS-16301
> URL: https://issues.apache.org/jira/browse/HDDS-16301
> Project: Apache Ozone
> Issue Type: New Feature
> Reporter: Mohammadhani Fouladgar
> Assignee: Mohammadhani Fouladgar
> Priority: Major
>
> An admin or orchestration step can transfer SCM leadership to a freshly-added
> SCM that is a committed Ratis peer but not yet operationally ready (in safe
> mode, no DataNode heartbeats, empty NodeManager view). Nothing rejects such a
> transfer today, so the new leader cannot allocate blocks or manage pipelines
> and client/DN operations stall until it is ready or leadership moves again.
> Scope is the explicit leadership-transfer request only; natural Ratis
> elections are not gated here
