---------------------------------------------
You should update, this was fixed in 17adf8e4f72114d336140fac5157a35e63d1f53a
> system.peers.tokens is empty after node restart

> Reporter: Pierre Chalamet
> Assignee: Sylvain Lebresne
> Priority: Minor

> 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;
