i-emek opened a new issue, #30965:
URL: https://github.com/apache/beam/issues/30965
### What happened?
'm having a Google dataflow job, I'm using apache beam ReadFromKafka to
consume topic messages. I'm consuming 4 topics. The pipeline used to work fine,
after we added a new broker to our kafka cluster and triggered a rebalancing,
the consumer started failing on one specific topic but successfully kept
working for the other 3 topics.
Same behaviour noticed when creating a new consumer group also
`The error is: org.apache.kafka.common.errors.TimeoutException: Timeout of
60000ms expired before the position for partition topic_name-0 could be
determined `
Here is the code:
`(
pcoll
| f"Read From Kafka {self.transf_label}"
>> ReadFromKafka(
consumer_config=self.kafka_consumer_config,
topics=_topic_list,
with_metadata=True,
)
| f"Extract KVT {self.transf_label}" >>
Map(extract_key_value_topic)
| f"Decode messages {self.transf_label}" >>
ParDo(DecodeKafkaMessage())
)`
My config
```
{
"bootstrap.servers": BROKERS,
"security.protocol": SECURITY_PROTOCOL,
"sasl.mechanism": SASL_MECHANISM,
"group.id": "consumer-group-dummy",
"session.timeout.ms": "60000",
"sasl.jaas.config":
f'org.apache.kafka.common.security.scram.ScramLoginModule required
username="{SASL_USERNAME}" password="{SASL_PASSWORD}";',
"auto.offset.reset": "latest",
}
```
One thing to consider is our other Kafka consumer apps are not throwing any
issue, this behavior is noticed only with the apache beam pipeline. Also when I
tried to trigger locally a consumer with the same config and same consumer
group using Kafka confluent library and simple python script, it seems to be
working fine and pulling the messages.
I'm wondering if this is a bug from the expansion server which is using
Kafka IO
