> Thin client: cluster group returns cached nodes after cluster restart
> ---------------------------------------------------------------------

> Key: IGNITE-21001
> URL: https://issues.apache.org/jira/browse/IGNITE-21001
> Project: Ignite
> Issue Type: Bug
> Reporter: Nikita Amelchev
> Assignee: Mikhail Petrov
> Priority: Critical
> Labels: ise
> Fix For: 2.17
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> When a client requests information about cluster nodes, it sends the version
> of the topology for which it received a list of cluster nodes the previous
> time.
> And if the client's version of the topology matches the one currently on the
> server, then the server does not send the list of cluster nodes back to the
> client. Like the client knows everything itself.
> But after full cluster restart, the topology version may not change. But the
> nodes will be different.
> The reproducer:
> {noformat}
> @Test
> public void testClusterGroup() throws Exception {
> IgniteEx srv = startGrid(0);
> try (IgniteClient client = startClient(0)) {
> assertTrue(client.cluster().nodes().contains(srv.localNode()));
> stopAllGrids();
> srv = startGrid(0);
> assertTrue(client.cluster().nodes().contains(srv.localNode()));
> }
> }
> {noformat}
