Mikhail Petrov updated IGNITE-21001:
------------------------------------
Description:
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 restarting the cluster, 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}
