Hudson commented on CASSANDRA-437:
----------------------------------

Integrated in Cassandra #208 (See 
[http://hudson.zones.apache.org/hudson/job/Cassandra/208/])
    record gossipped enpoint/token pairs as we see them.  also clean up 
SystemTable code to avoid unnecessary CF fetches.  patch by Gary Dusbabek and 
jbellis for 


> record token/endpoint (ip) pairs in system table

> Each node records its own token after generating one or reading it from the 
> config file.  For more redundancy we should record others'  tokens too.
> This should not be regarded as canonical information -- do not use it to take 
> shortcuts instead of using gossip.  It is only to provide redundancy in case 
> of failure.
> For instance, if your cluster loses power and when it comes back up, the disk 
> w/ token information on one of your machines is dead, this will let you get 
> that token information easily from another node instead of having to guess by 
> scanning sstables.  This is not a theoretical scenario; something of this 
> nature did happen to FB.
