NPE aborts streaming operations for keyspaces with hyphens ('-') in their names
-------------------------------------------------------------------------------

                 Key: CASSANDRA-1377
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1377
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 0.6.3
            Reporter: Ben Hoyt


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.
