Subject Re: How does Bootstrapping work in 0.7 ??
Date Thu, 20 Jan 2011 19:55:00 GMT
Patrick, if you try adding capacity again from the beginning, I'd be curious
to hear if the DataStax/Riptano<http://www.datastax.com/docs/0.7/operations/clustering#adding-capacity>docs
are helpful or not.

Also, in the Getting Started
page<http://www.datastax.com/docs/0.7/getting_started/index>,
we note that it may be best to set initial_token to 0 on the very first node
that you start.

Regards,

Eric Gilmore
