> Using a 2 nodes fresh cluster (127.0.0.1 & 127.0.0.2) running latest 1.2, I’m querying
system.peers to get the nodes of the cluster and their respective token. But it seems there
is a problem after either node restart.
> When both node starts up, querying system.peers seems ok:
> {code}
> 127.0.0.1> select * from system.peers;
