Suraj Menon commented on HAMA-664:
----------------------------------
You should be able to do a
{noformat}
out.close();
byte[] byteArray = outArray.toByteArray();
{noformat}
The size of byteArray is the size of message.
I checked the patch. If you are able to achieve the desired results with
sampling, you won't need it anyways.

> I noticed that calculation of bundle object size in Avro RPC and Hadoop RPC
