> Key: CASSANDRA-437
> URL: https://issues.apache.org/jira/browse/CASSANDRA-437
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Jonathan Ellis
> Assignee: Sammy Yu
> Fix For: 0.5

>
> 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.
