-------------------------------------------

             Summary: Wrong toString() of CQL3Type.Collection
                 Key: CASSANDRA-6051
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6051
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Alexander Radzin
            Priority: Minor


{{Collection}} is an inner class of {{CQL3Type}} that represents column types that can contain several values (lists, sets, maps). Its {{toString()}} is very helpful: it generates a string representation of type that can be used for generating of {{CREATE TABLE}} statement. 

Unfortunately this method works incorrectly for maps. Instead of returning something like {{map<text, int>}} it returns {{set<text, int>}}.

Here is the appropriate code fragment:

{code:title=CQL3Type$Collection.java|borderStyle=solid}
       public String toString()
        {
            switch (type.kind)
            {
                case LIST:
                    return "list<" + ((ListType)type).elements.asCQL3Type() + ">";
                case SET:
                    return "set<" + ((SetType)type).elements.asCQL3Type() + ">";
                case MAP:
                    MapType mt = (MapType)type;
                    return "set<" + mt.keys.asCQL3Type() + ", " + mt.values.asCQL3Type() + ">";
            }
            throw new AssertionError();
        }
{code}


The obvious bug is here:
{code:java}
                case MAP:
                    MapType mt = (MapType)type;
                    return "set<" + mt.keys.asCQL3Type() + ", " + 
{code}

It should be {{"map<" + ...}} instead of {{"set<" + ...}}
