In both cases it looks like an event is firing before HOST_ID or TOKENS
respectively are being set.
To reproduce I use ccm to run a 3 node cluster, replication factor 2. I load
about 70k rows at CL = ONE, read them back at CL = ALL, and then restart all of
the nodes.

> Key: CASSANDRA-4383
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4383
> Project: Cassandra
> Issue Type: Sub-task
> Reporter: Brandon Williams
> Assignee: Brandon Williams
> Fix For: 1.2.0 beta 1

> Since after CASSANDRA-4317 we can know which version a remote node is using
> (that is, whether it is vnode-aware or not) this a good opportunity to change
> the token encoding to binary, since with a default of 256 tokens per node
> even a fixed-length 16 byte encoding per token provides a great deal of
> savings in gossip traffic over a text representation.
