-----------------------------------------------------------------------
This will certainly affect scenarios where nodes don't already have this
information, such as after a complete cluster restart where some nodes are left
down, and a new one attempts to bootstrap. It will never have complete
information about the ring for token selection.

> Key: CASSANDRA-16561
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16561
> Project: Cassandra
> Issue Type: Bug
> Components: Cluster/Gossip
> Reporter: Brandon Williams
> Priority: Normal
> Fix For: 2.2.x, 3.0.x, 3.11.x, 4.0.x
>
>
> Originally when we began persisting host information such a tokens/host_id,
> we would populate gossip with this information. At some point we began only
> populating TokenMetadata, which gives us most of the same benefit, but in a
> full ring restart where the gossip ether is empty, it populates useless info
> such as :
> {quote}
> /10.101.32.212
> generation:0
> heartbeat:0
> TOKENS: not present
> {quote}
> which is the minimum required for a state to exist. Instead we should keep
> gossip in sync with TMD when populating this information like we used to do.
