>             Project: Cassandra
>          Issue Type: Bug
>    Affects Versions: 1.2.0 beta 1
>         Environment: Cassandra 937f15e1
> OS X 10.8.2
> java version "1.6.0_35"
> Java(TM) SE Runtime Environment (build 1.6.0_35-b10-428-11M3811)

> I'm putting a collection onto the wire in an EXECUTE request with exactly the same bytes
that Cassandra encodes the same data in a response:
> "Can't apply operation on column with org.apache.cassandra.db.marshal.SetType(org.apache.cassandra.db.marshal.UTF8Type)
type"
> Here's the full trace log from cassandra:
> {noformat}
> DEBUG 19:24:15,414 Received: PREPARE INSERT INTO things (id, set_text) VALUES (?, ?);
> TRACE 19:24:15,414 CQL QUERY: INSERT INTO things (id, set_text) VALUES (?, ?);
> TRACE 19:24:15,415 Stored prepared statement #413587006 with 2 bind markers
> DEBUG 19:24:15,415 Responding: RESULT PREPARED 413587006 [id(gocql_collections, things),
org.apache.cassandra.db.marshal.TimeUUIDType][set_text(gocql_collections, things), org.apache.cassandra.db.marshal.SetType(org.apache.cassandra.db.marshal.UTF8Type)]
> DEBUG 19:24:15,416 Received: EXECUTE 413587006 with 2 values
> TRACE 19:24:15,416 [1] 'java.nio.HeapByteBuffer[pos=18 lim=34 cap=53]'
> TRACE 19:24:15,416 [2] 'java.nio.HeapByteBuffer[pos=38 lim=51 cap=53]'
> DEBUG 19:24:15,417 Responding: ERROR INVALID: Can't apply operation on column with org.apache.cassandra.db.marshal.SetType(org.apache.cassandra.db.marshal.UTF8Type)
type.
> {noformat}
> The prepared statement is:
> {noformat}
> INSERT INTO things (id, set_text) VALUES (?, ?);
> {noformat}
> and the collection value ({'asdf', 'sdf'}) is encoded as:
> {noformat}
> 00 02 00 04 61 73 64 66 00 03 73 64 66
> {noformat}
> which is byte-for-byte exactly the same as what I get from Cassandra off the wire when
I do a query for the same data.
> I already have the driver working with other queries/inserts with all other types, so
this is just a collection encoding problem.
