Jun Rao commented on CASSANDRA-348:
-----------------------------------
Interesting. It seems the problem is that you started with a key that's in the
middle btw 2 adjacent tokens and you need to go back to the very first node to
complete the full scan. The current code seems to stop as soon as you hit the
first node again. It seems that this will happen whether you roundup or
rounddown. So, maybe we should let the first node be scanned twice, one at the
beginning and another at the end.

> I've got two nodes with tokens 00000000 and 88888888. I add 16 rows in which
> are spread over them, then do a key range scan.
> I can scan part of the range successfully, but if I try to scan the entire
> range of keys (0-f) then I get unexpected results

> All of which returned as I expected.
