Edward J. Yoon commented on HAMA-664:
-------------------------------------

There's no need to calculate exact size. So, I'll calculate approximate the size using Java Runtime memory utils.

> I noticed that calculation of bundle object size in Avro RPC and Hadoop RPC causes significant performance decrease and uses huge resources.
> We should get rid of this and figure out another way to convert byte array.

>       DataOutputStream out = new DataOutputStream(outArray);
>       msg.write(out);
>       out.close();
>       byte[] byteArray = outArray.toByteArray();
