Eric Bowman updated KAFKA-3011:
-------------------------------
Description:
Because of this loop in ConsumerNetworkClient:
{code:java}
public void awaitMetadataUpdate() {
int version = this.metadata.requestUpdate();
do {
poll(Long.MAX_VALUE);
} while (this.metadata.version() == version);
}
{code}
...if Kafka is not reachable (perhaps not running, or other network issues,
unclear), then KafkaConsumer.poll(0) will block until it's available.
I suspect that better behavior would be an exception
