Gossiper misses first update (?) when restarting a node
-------------------------------------------------------

                 Key: CASSANDRA-515
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-515
             Project: Cassandra
          Issue Type: Bug
            Reporter: Jonathan Ellis
            Assignee: Jonathan Ellis
            Priority: Minor
             Fix For: 0.5


Easy way to reproduce:

Start node A.
Start node B, with autobootstrap=false.
Kill B, wipe data dir, and restart (still w/ autobootstrap=false).

A will show B as down, with its old token.  (B will see both nodes correctly.)

This appears to be because when you wipe data dir, generation restarts at 1.  
(This is not just operator error; besides during testing, this could arise if a 
node dies completely and has to be replaced.)

It appears that initializing the generation to seconds-since-epoch would fix 
this.
