> Project: Ratis
> Issue Type: Bug
> Reporter: Jinglun
> Assignee: Jinglun
> Priority: Major
> Attachments: merbership_new_peere_initial_group_problem.pdf
>
>
> Supposing we want to replace 2 peers from a 3 peers cluster. Normally we
> start the 2 new peers with empty conf. This can cause an infinity election
> and make the cluster unavailable forever.
>
> I will upload a patch to describe the case. And I will upload a document to
> describe the current dilemma when performing membership changes.
>
> TestMembership simulates the 'replacing 2 peers from a 3 peers cluster'
> issue. It ends with an infinity leader election.
