Jonathan Ellis commented on CASSANDRA-2045:
-------------------------------------------

bq. state.hasToken() is set in the Gossiper's status check, which won't have 
happened when the onAlive event is sent to SS.

It looks to me though like once set it's permanent.  How does it get un-set?

> Currently when HH is enabled, hints are stored, and when a node comes back, 
> we begin sending that node data. We do a lookup on the local node for the row 
> to send. To help reduce read load (if a node is offline for long period of 
> time) we should store the data we want forward the node locally instead. We 
> wouldn't have to do any lookups, just take byte[] and send to the destination.
