Subject RE: Specifying initial token in 1.2 fails

Yes indeed - my mistake.  Thanks.  I can specify RandomPartitioner, since I do not use indexing
- yet.

Just for informational purposes - with Murmur3 - to achieve a balanced cluster - is the initial
token method supported?
If so - how should these be generated, the token-generator seems to only apply to RandomPartitioner.

Thanks again

Murmur3 != MD5 (RandomPartitioner)

Subject: Specifying initial token in 1.2 fails

Hi

Just started evaluating 1.2 - starting a clean Cassandra node - the usual practice is to specify
the initial token - but when I attempt to start the node the following is observed:

INFO [main] 2013-01-03 14:08:57,774 DatabaseDescriptor.java (line 203) disk_failure_policy

This looks like a bug.

Thanks
