Cassandra: how to create a COLUMN FAMILY with Leveled Compaction?

My stupid simple question is: how to create a COLUMN FAMILY with Leveled Compaction in Cassandra 1.1+?

There is no example in documentation:
http://www.datastax.com/docs/1.1/configuration/storage_configuration#compaction-strategy

I try it on Cassandra 1.1.0 and 1.1.2, both failed. The COLUMN FAMILY is still 'SizeTieredCompactionStrategy'.  :(

Here is my test and output:

@host01:/usr/share/cassandra>cqlsh host01 --cql3
Connected to BookCluster at host01:9160.
[cqlsh 2.2.0 | Cassandra 1.1.0 | CQL spec 3.0.0 | Thrift protocol 19.30.0]
Use HELP for help.

cqlsh> use demo;

cqlsh:demo> CREATE COLUMNFAMILY book
        ... (isbn varchar,
        ...  book_id bigint,
        ...  price int,
        ...  obj varchar,
        ...  PRIMARY KEY (isbn, book_id)
        ... )
        ... WITH compaction_strategy_class='LeveledCompactionStrategy';
cqlsh:demo>
cqlsh:demo> describe COLUMNFAMILY book;

CREATE COLUMNFAMILY book (
  isbn text PRIMARY KEY
) WITH
  comment='' AND
  comparator='CompositeType(org.apache.cassandra.db.marshal.LongType,org.apache.cassandra.db.marshal.UTF8Type)'
AND
  read_repair_chance=0.100000 AND
  gc_grace_seconds=864000 AND
  default_validation=text AND
  min_compaction_threshold=4 AND
  max_compaction_threshold=32 AND
  replicate_on_write=True AND
  compaction_strategy_class='SizeTieredCompactionStrategy' AND
  compression_parameters:sstable_compression='org.apache.cassandra.io.compress.SnappyCompressor';

update:

it's been fixed since Cassandra 1.1.5
