Manu Zhang commented on KAFKA-725:
----------------------------------
I can reproduce this on 0.9.0.0. The error log is
[2016-01-28 16:12:32,840] ERROR [Replica Manager on Broker 1]: Error processing
fetch operation on partition [ad-events,1] offset 75510318
(kafka.server.ReplicaManager)
I also print the sent offset from producer
time partition offset
16:12:32.840 1 75510318
It seems the offset is produced and consumed at the same time.
> Broker Exception: Attempt to read with a maximum offset less than start offset
