Mikhail Stepura commented on CASSANDRA-7267:
--------------------------------------------

Here is the thing. There are 2 sets in the result, one is embedded in an user type ({{members}} and one is 'standalone'({{tags}}). The problem is that the server send the length of a 'standalone' set as a 2byte short value and the length for the 'embedded' as a 4byte integer.

The python-driver (1.1.2 in this case) always expects 2 bytes, so it fails to decode the set

> Hi,
> i just played around with Cassandra 2.1.0 beta2 and i might have found an issue with embedded Sets in User Defined Data Types.
> Here is how i can reproduce it:
> 1.) Create a keyspace "test"
> 2.) Create a table like this:
> {{create table songs (title varchar PRIMARY KEY, band varchar, tags Set<varchar>);}}
> 3.) Create a udt like this:
> {{create type band_info_type (founded timestamp, members Set<varchar>, description text);}}
> 4.) Try to insert data:
> {code}
> insert into songs (title, band, band_info, tags) values ('The trooper', 'Iron Maiden', {founded:188694000, members: {'Bruce Dickinson', 'Dave Murray', 'Adrian Smith', 'Janick Gers', 'Steve Harris', 'Nicko McBrain'}, description: 'Pure evil metal'}, {'metal', 'england'});
> {code}
> 5.) Select the data:
> {{select * from songs;}}
> Returns this:
> {code}
> The trooper | Iron Maiden | {founded: '1970-01-03 05:24:54+0100', members: {}, description: 'Pure evil metal'} | {'england', 'metal'}
> {code}
> The embedded data-set seems to empty. I also tried updating a row which also does not seem to work.
> Regards,
> Thomas
