Subject [jira] Commented: (CASSANDRA-781) in a cluster, get_range_slice() does not return all the keys it should

Hernan Badenes commented on CASSANDRA-781:
------------------------------------------

Great, thank you. The testcases for the current fix seem thorough, but if it helps I can do
the testing with my own data as soon as a new patch is available.

> get_range_slice() does not return the same set of keys as get_key_range() in 0.5.0 final.
> I posted a program to reproduce the behavior:
> http://www.mail-archive.com/cassandra-dev@incubator.apache.org/msg01474.html
> Apparently, you must have more than one node to get the behavior. Also, it may depend
on the locations of the nodes on the ring.. I.e., if you don't generate enough keys randomly,
then by chance they could all fall on the same host and you might not see the behavior, although
I was able to get it to happen using only 2 nodes and 10 keys.
