Try turning up the logging on the server side to DEBUG and see what it says. Chances are you
are not sending what you think you are. 

Or if you feel like it put a breakpoint in o.a.c.thrift.Cassandra$Client.send_insert to see
how when the client is doing. 

I agree with Tyler, higher level clients are *much* easier. But it's sometimes fun to see
what's happening on the inside.

Is there a particular reason why you're not using a high level client?

Raw thrift is painful in many ways.

I'm trying to insert a super column but I can't get passed this error.

this is the code I'm calling:
client = new Cassandra.Client(protocol, protocol)
client.insert(key, columnParent, c, level)

And the values from the debugger:
key = {java.nio.HeapByteBuffer@3168}  "java.nio.HeapByteBuffer[pos=0 lim=16 cap=16]"
columnParent = {org.apache.cassandra.thrift.ColumnParent@3169}  "ColumnParent(column_family:Super,

6C 75 65, timestamp:1291243840220)"

I can insert a standard column without any issues with the same codebase..  What column name
must not be empty??  Clearly it's not.  What am I missing?
