Re: kafka corrupt record exception

[Dominik Wosiński]

Hey,
Sorry for such a delay, but I have missed this message. Basically,
technically you could have Kafka broker installed in version say 1.0.0  and
using  FlinkKafkaConsumer08. This could technically create issues.
I'm not sure if You can automate the process of skipping corrupted
messages, as You would have to write the consumer that will allow skipping
messages that are corrupted. This maybe a good idea to think about for
Flink though.

On the other hand, if You have many messages that are corrupted, this may
mean that the problem lies elsewhere within You pipeline (kafka producers
before Flink).

Re: kafka corrupt record exception

[Dominik Wosiński]

Hey,
As far as I understand the error is not caused by the deserialization but
really by the polling of the message, so custom deserialization schema
won't really help in this case. There seems to be an error in the messages
in Your topic.

You can see here
what
is the data that should be associated with the message. One thing you could
possibly do is simply find the offset of the corrupted message and start
reading after the record. However, You should probably verify what is the
reason for the message size being smaller than it should. One thing that
can cause this exact behavior may be a mismatch between Kafka versions on
broker and consumer.

Best Regards,
Dom.

According to docs (here: 
https://ci.apache.org/projects/flink/flink-docs-stable/dev/connectors/kafka.html#the-deserializationschema
 

 , last paragraph) that’s an expected behaviour. May be you should think about 
writing your own deserialisation schema to skip corrupted messages.

Re: kafka corrupt record exception

[Sushant Sawant]

Hi,
Thanks for reply.
But is there a way one could skip this corrupt record from Flink consumer?
Flink job goes in a loop, it restarts and then fails again at same record.

Hi
As you said, consume from ubuntu terminal has the same error, maybe you could 
send a email to kafka user maillist.

Best, Congxian

kafka corrupt record exception

[Sushant Sawant]

Hi team,
I am facing this exception,

org.apache.kafka.common.KafkaException: Received exception when fetching
the next record from topic_log-3. If needed, please seek past the record to
continue consumption.

Caused by: org.apache.kafka.common.errors.CorruptRecordException: Record
size is less than the minimum record overhead (14)


Also, when I consume message from ubuntu terminal consumer, I get same
error.

How can skip this corrupt record?
