Create CF with composite column through CQL 3

[Wei Zhu]

I try to use CQL3 to create CF with composite columns,

 CREATE TABLE Friends (
         ...     user_id bigint,
         ...     friend_id bigint,
         ...     status int,
         ...     source int,
         ...     created timestamp,
         ...     lastupdated timestamp,
         ...     PRIMARY KEY (user_id, friend_id, status, source)
         ... );


When I check it with cli, the composite type is a bit odd, why it's defined as 
Long, Int32, Int32, UTF8, is it supposed to be Long, Long, Int32, Int32? Did 
I do something wrong?

 describe friends;
    ColumnFamily: friends
      Key Validation Class: org.apache.cassandra.db.marshal.LongType
      Default column value validator: org.apache.cassandra.db.marshal.UTF8Type
     Columns sorted by: org.apache.cassandra.db.marshal.CompositeType(
org.apache.cassandra.db.marshal.LongType,
org.apache.cassandra.db.marshal.Int32Type,
org.apache.cassandra.db.marshal.Int32Type,
org.apache.cassandra.db.marshal.UTF8Type)
      GC grace seconds: 864000
      Compaction min/max thresholds: 4/32
      Read repair chance: 0.1
      DC Local Read repair chance: 0.0
      Replicate on write: true
      Caching: KEYS_ONLY
      Bloom Filter FP chance: default
      Built indexes: []
      Compaction Strategy: 
org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy
      Compression Options:
        sstable_compression: org.apache.cassandra.io.compress.SnappyCompressor

Thanks.
