-------------------------------------
I cannot copy/paste the stack track...sorry, not "can"
> IndexOutOfBounds in RecordsIterator causes infinite loop in NetworkClient

> Key: KAFKA-4224
> URL: https://issues.apache.org/jira/browse/KAFKA-4224
> Project: Kafka
> Issue Type: Bug
> Components: consumer
> Affects Versions: 0.10.0.1
> Reporter: Michael Coon
>
> For whatever reason, I seem to have a corrupted message that is returned from
> a broker that puts the consumer into an infinite loop. The
> org.apache.kafka.client.consumer.internals.Fetcher (line 590) is getting the
> next record from the RecordsIterator or MemoryRecords but when it attempts to
> decode the record, it throws "IndexOutOfBounds" exception. Unfortunately,
> that exception is merely logged and the Fetcher goes on to get the next
> message. But the exception apparently does not move the underlying buffer
> read forward in such a way that it would actually go and get the next record.
> The result: it keeps trying to read the corrupted record but can't make
> progress.
> I offer two potential solutions:
> 1) throw the exception up to me and let me figure out whether I want to skip
> forward in offsets
> 2) Make sure the underlying RecordsIterator actually moves forward on
> exceptions so that progress can be made when corrupted messages are found.
