Jun Rao resolved KAFKA-1303.
----------------------------
Resolution: Won't Fix
I think this is less of an issue given that we have
max.in.flight.requests.per.connection in the producer config. So, closing this
for now.

> While debugging a system test, I observed the following.
> 1. A broker side configuration
> (replica.fetch.wait.max.ms=500,replica.fetch.min.bytes=4096) made the time to
> complete a produce request long (each taking about 500ms with ack=-1).
> 2. The producer client has a bunch of outstanding produce requests queued up
> on the brokers.
> 3. One of the brokers fails and we force updating the metadata.
> 4. The metadata request is queued up behind those outstanding producer
> requests.
> 5. By the time the metadata response comes back, some messages have failed
> all retries because of stale metadata.
