Many thanks for the answer. Trying to switch from Hazelcast 5.x to the ignine 3, I'd like to ask one additional question if I may - after trying to init a cluster from embedded mode for the topology setup of 3 nodes I always get repeatedly a following error without forming a cluster (running all nodes on my laptop):
....
WARNING: Node <metastorage_group/node3> PreVote to node2
latency=Status[ENOENT<1012>: Peer id not found: node2, group:
metastorage_group] error: 4.

logInternal
WARNING: Node <metastorage_group/node3> PreVote to node1
latency=Status[ENOENT<1012>: Peer id not found: node1, group:
metastorage_group] error: 4.
....
even though it's visible in the log that topology was recognized properly:
....
INFO: Topology snapshot [nodes=[node1, node2, node3]]
....
Attaching the config of one node (another nodes differ just by ports) and
here is the code snippet to trigger a cluster initialization:
try {
IgniteServer node = IgniteServer.start("node3", configFilePath, workDir);
//wait probably a bit?
Thread.sleep(1000);
InitParameters initParameters = InitParameters.builder()
.metaStorageNodeNames(List.of("node1", "node2", "node3"))
.clusterName("cluster")
.build();
node.initCluster(initParameters);
} catch (Throwable e) {
e.printStackTrace();
}
Any idea why this voting can't be established?
Thanks in advance
Best regards
