Subject [jira] [Commented] (CASSANDRA-13369) If there are multiple values for a key, CQL grammar choses last value. This should not be silent or should not be allowed.

> If through CQL, multiple values are specified for a key, grammar parses the map and last
value for the key wins. This behavior is bad.
> e.g. 
> {code}
> CREATE KEYSPACE Excalibur WITH REPLICATION = {'class': 'NetworkTopologyStrategy', 'dc1':
2, 'dc1': 5};
> {code}
> Parsing this statement, 'dc1' gets RF = 5. This can be catastrophic, may even result
in loss of data. This behavior should not be silent or not be allowed at all.
