Vijay commented on CASSANDRA-3555:
----------------------------------

Looks like (1) is not a problem we do throw exception if no seeds seen.
if (endpoints.isEmpty())
            throw new RuntimeException("No other nodes seen!  Unable to bootstrap."

> We might want to handle failures in bootstrapping:
> 1) When none of the Seeds are available to communicate then throw exception
> 2) When any one of the node which it is bootstrapping fails then try next in the list (and if the list is exhausted then throw exception).
> 3) Clean all the existing files in the data Dir before starting just in case we retry.
> 4) Currently when one node is down in the cluster the bootstrapping will fail, because the bootstrapping node doesnt understand which one is actually down.
> Also print the nt ring in the logs so we can troubleshoot later if it fails.
> Currently if any one of the above happens the node is skipping the bootstrap or hangs.
