Both nodes own 100% of cluster
What does the it mean that each node owns effective 100% of cluster? Both
nodes report same output.

Yes, for instance I have 6 nodes and have 50% ownership because I have RF=3, and 6/3 = 2 virtual entities that are written to which means each node owns 50%.

I don't know cassandra 1.2 very well, 100% of effective own probably probably means that you're running with RF = number of nodes.

These are running the latest Cassandra 1.2 with 256 vnodes each.

Why have u assigned for both nodes a genenerated token? And how you calculated it?
Shouldnt u choose one of them to has its token as the '0' start value?
At least that is what is said on the tutorials I've read.

Why have u assigned for both nodes a genenerated token? And how you
calculated it?
Shouldnt u choose one of them to has its token as the '0' start value?
At least that is what is said on the tutorials I've read.
