------------------------------------
Summary: KafkaConsumer.committed(...) hangs forever if port number
is wrong
Key: KAFKA-3457
URL: https://issues.apache.org/jira/browse/KAFKA-3457
Project: Kafka
Issue Type: Bug
Components: clients
Affects Versions: 0.9.0.1
Reporter: Harald Kirsch
Create a KafkaConsumer with default settings but with a wrong host:port setting
for bootstrap.servers. Have it in some consumer group, do not subscribe or
assign partitions.
Then call .committed(...) for a topic/partition combination a few times. It
will hang on the 2nd or third call forever. In the debug log you will see that
it repeats connections all over again. I waited many minutes and it never came
back to throw an Exception.
The connections problems should at least pop out on the WARNING log level.
Likely the connection problems should throw an exception eventually.
