Edward Smith commented on KAFKA-279:
------------------------------------

I tested this and verified that this fixes the error for --batch-size.

> 2. When I do bin/kafka-console-producer.sh --timeout 30000   --zookeeper localhost:2181
--topic test1
> I would think that console-producer would wait for 30s if the batch size (default 200)
is not full. It doesn't. It takes the same time without the timeout parameter (default 1000)
and dumps whatever the batch size.
> Resolution from Jun
> 1. The code does the following to set batch size
>      props.put("batch.size", batchSize)
> Instead, it should do
>      props.put("batch.size", batchSize.toString)
> 2. It sets the wrong property name for timeout. Instead of doing
>    props.put("queue.enqueueTimeout.ms", sendTimeout.toString)
> it should do
>    props.put("queue.time", sendTimeout.toString)
