Peter Lee commented on HDDS-11839:
----------------------------------
I tried this:
{code:java}
private String getRaftPeerId(String newLeaderId, SCMRatisServer scmRatisServer)
{
String raftPeerID = null;
String serviceID = config.get(ScmConfigKeys.OZONE_SCM_SERVICE_IDS_KEY);
String scmHostName =
config.get(ConfUtils.addKeySuffixes(OZONE_SCM_ADDRESS_KEY, serviceID,
newLeaderId));
Optional<RaftPeer> raftPeer =
scmRatisServer.getDivision().getGroup().getPeers().stream()
.filter(peer -> (peer.getAddress().equals(scmHostName)))
.findFirst();
if (raftPeer.isPresent()) {
raftPeerID = raftPeer.get().getId().toString();
} else {
// log out newleaderId and the address of all the scm nodeIds
LOG.error("Cannot find the raft peer for the new leader id: {} in scm
nodeIds: {}", newLeaderId, scmRatisServer
.getDivision().getGroup().getPeers().stream().map(RaftPeer::getAddress).collect(Collectors.toList()));
}
return raftPeerID;
}
{code}
and get:
{code:java}

> Labels: newbie
>
> Leadership transfer expects leader to be identified by UUID for SCM, but node
> ID for OM:
> {code}
> $ ozone admin scm transfer --new-leader-id scm1
> Target scm1 not found in group [891cd056-3cf1-4e52-9cac-eff0af7bfefe,
> b25f513f-ddf7-4382-a3f0-fe5b209a7a26, ac63c8ae-1f4c-4fa7-9eed-e279d0b573ff].
> $ ozone admin om transfer --new-leader-id om1
> Transfer leadership successfully to om1.
> {code}
> Ideally it should accept both kinds of ID.
