["Jing Zhao (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/RATIS-86?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16016320#comment-16016320 ] 

Jing Zhao commented on RATIS-86:
--------------------------------

Thanks for the patch, Nicholas! The patch looks good to me. Just two minor comments:
# Do you think we can rename ManagementProtocol to RaftGroupAdminProtocol?
# Semantically ReinitializeRequest may not be a subclass of SetConfigurationRequest. Later if we support multiple raft groups then these two requests may diverge: ReinitializeRequest will initialize/add a raft group, and SetConfigurationRequest will change the members of raft group.

> When a RaftServer is built, it creates a RaftServerImpl object and starts running a RaftServerRpc service.  The RaftServerImpl captures ServerState including RaftLog and RaftConfiguration.
> We want to support server re-initialization so that a server can support multiple raft clusters sequentially.  This is our first step to support multi-raft.
