gaoyajun02 updated RATIS-2323:
------------------------------
Description:
In the Celeborn master cluster, the Leader's clientAddress and adminAddress are
cached in Followers and used as the RPC endpoint for handling client requests.
When a Follower receives a client request, since only the Leader can process
client requests, the Follower returns the Leader's RPC endpoint to the client,
allowing the client to resend the request directly to the Leader.
When expanding the master cluster, we currently use the ratis-shell's add
operation. However, peers added through this operation lack clientAddress and
adminAddress settings. If a newly added peer becomes the Leader, all Followers
will return an empty address, causing clients to access an incorrect Leader
address (127.0.0.1).
Therefore, we propose extending the ratis-shell add command to support setting
clientAddress and adminAddress parameters when adding new peers to the cluster.
