Hi Kuan Po Tseng, It is not possible to add a new controller purely by ID. You need controller ID, directory ID, and controller endpoints.
These cannot be obtained through describeMetadataQuorum since that only describes the existing quorum, not what you would like the new one to be. Also, obviously, we never want to reuse an existing directory ID. Therefore I will vote -1 on this pending further discussion. best, Colin On Tue, Apr 22, 2025, at 08:56, Kuan Po Tseng wrote: > Hello everyone, > > I would like to start a vote on KIP-1141, thank you! > > KIP: https://cwiki.apache.org/confluence/x/PZFEF > Discussion thread: > https://lists.apache.org/thread/mq5n8j8w0ycg9fhd1m4zcc2ctrgfd0d4 > > Best, > Kuan-Po Tseng
