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

             Summary: TTL/WRITETIME function against collection column returns 
invalid value
                 Key: CASSANDRA-4992
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4992
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 1.2.0 beta 2
            Reporter: Yuki Morishita
            Priority: Minor


Since we cannot query individual content of collection in 1.2, TTL/WRITETIME 
function on collection column does not make sense. But currently we can perform 
those function on collection and get deserialization error like:

{code}
value '\x00\x03\x00\x01c\x00\x01b\x00\x01a' (in col 'writetime(l)') can't be 
deserialized as bigint: unpack requires a string argument of length 8
{code}

Looks like it tries to deserialize whole list/set/map content as bigint for 
WRITETIME and int for TTL.
