Erik Onnen commented on CASSANDRA-1377:
---------------------------------------
Thanks Jonathan. I added one additional patch to relax things slightly in 0.7
trunk. Tested with a nodetool loadbalance and nodetool move with a two node
ring and both worked fine. Lots of changes in the streaming code between 0.6
and 0.7 and it looks like the broken code didn't move forward into 0.7 near as
I can tell in reading though it.

> Affects Versions: 0.6.3
> Reporter: Ben Hoyt
> Assignee: Gary Dusbabek
> Fix For: 0.6.5, 0.7 beta 2

> When streaming starts for operations such as repair or bootstrap, it will
> fail due to an NPE if they rows are in a keyspace that has a hyphen in its
> name. One workaround for this issue would be to not use keyspace names
> containing hyphens. It would be even nicer if streaming worked for keyspace
> names with hyphens, since keyspaces named like that seem to be fine in all
> other ways.
> To reproduce:
> 1. With a multi-node ring, load up a keyspace with a hyphen in its name
> 2. Add some data to that keyspace
> 3. nodetool repair
> Expected results:
> Repair operations complete normally
> Actual results:
> Repair operations don't complete normally. The stacktrace below is
> correlated with the repair request.
