Why doesn't processing and pasting from the CLIS Cassandra tutorial work?

Following a bit of http://wiki.apache.org/cassandra/CassandraCli , and can anyone explain this?

Before running any set command in the Cassandra CLI, it is always recommended that you do the following:

assume <column_family> keys as utf8;
assume <column_family> comparator as utf8;
assume <column_family> validator as utf8;

This ensures that everything you install and list is understood.

PS: This is only for beginners in Cassandra

This is for an older version of Cassandra. Keys are now treated as default hexadecimal bytes, so you need to:

set User[utf8('jsmith')]['first'] = 'John';

or do:

assume User keys as utf8;
set User['jsmith']['first'] = 'John';

Or, as noted in the document in the document:

. Cassandra 0.8, _validation_class :

update column family User with key_validation_class=UTF8Type;
+4
set User['jsmith'][utf8('first')] = utf8('John');

If you are not sure about the command set, you can enter help set;and it will show the full documentation.
