-------------------------------------
Summary: Broker Exception: Attempt to read with a maximum offset
less than start offset
Key: KAFKA-725
URL: https://issues.apache.org/jira/browse/KAFKA-725
Project: Kafka
Issue Type: Bug
Components: log
Affects Versions: 0.8
Reporter: Chris Riccomini
Assignee: Jay Kreps
I have a simple consumer that's reading from a single topic/partition pair.
Running it seems to trigger these messages on the broker periodically:
2013/01/22 23:04:54.936 ERROR [KafkaApis] [kafka-request-handler-4] [kafka] []
[KafkaApi-466] error when processing request (MyTopic,4,7951732,2097152)
java.lang.IllegalArgumentException: Attempt to read with a maximum offset
(7951715) less than the start offset (7951732).

When I shut the consumer down, I don't see the exceptions anymore.
This is the code that my consumer is running:
while(true) {
// we believe the consumer to be connected, so try and use it for a
fetch request
val request = new FetchRequestBuilder()
.addFetch(topic, partition, nextOffset, fetchSize)
.maxWait(Int.MaxValue)
// TODO for super high-throughput, might be worth waiting for
more bytes
.minBytes(1)
.build
debug("Fetching messages for stream %s and offset %s." format
(streamPartition, nextOffset))
val messages = connectedConsumer.fetch(request)
debug("Fetch complete for stream %s and offset %s. Got messages:
%s" format (streamPartition, nextOffset, messages))
if (messages.hasError) {
warn("Got error code from broker for %s: %s. Shutting down
consumer to trigger a reconnect." format (streamPartition,
messages.errorCode(topic, partition)))
ErrorMapping.maybeThrowException(messages.errorCode(topic,
partition))
}
messages.messageSet(topic, partition).foreach(msg => {
watchers.foreach(_.onMessagesReady(msg.offset.toString,
msg.message.payload))
nextOffset = msg.nextOffset
})
}
Any idea what might be causing this error?
