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

{code}
DataOutputStream out = new DataOutputStream(new BufferedOutputStream(outArray));
{code}

Thanks but how can I convert bundle object to outArray?

> 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();
> {code}
