Subject Re: Getting Exception when doing a range query using token (worked in 6.5 not in 6.6)
Date Tue, 16 Nov 2010 02:01:51 GMT
I only have 1 node (not a cluster), so not sure what another machine it is
trying to send to? This is a very basic test that I am doing, hence only 1
node.

I use describe_ring to get a list of TokenRanges (1 in this case) and use
the end_token and start_token from it to get_range_slices. So what should I
be doing instead?
