I need to create a ByteBuffer instance containing the proper= composite key, based on the values of the components of the key. I am goin= g to use it for update operation.

I tried to simply concatenate the buffers corresponding to t= he components, but I am not sure this is correct, because I am getting exce= ption that comes from the server :

 

InvalidRequestException(why:Not enough bytes to read value o= f component 0)

 

In the server log I see this:

 

org.apache.thrift.transport.TTransportException: Cannot read= . Remote side has closed. Tried to read 4 bytes, but only got 0 bytes. (Thi= s is often indicative of an internal error on the server side. Please check your server logs.)

 

(I believe here when it says “server side” it ac= tually means client, because it is the server’s log).

 

Seems like the buffer that my client sends is too short. &nb= sp;I suspect there is a way in thrift to do it properly, but I don’t = know how.

Looks like Hector has a Composite class that maybe can help,= but at this point I would really prefer to do it in Cassandra itself, with= out Hector.

 

Thanks!
