-----------------------------------------
Will do. Thanks.
> SimpleConsumer succeeds with embedded failure message
> -----------------------------------------------------
>
> Key: KAFKA-1968
> URL: https://issues.apache.org/jira/browse/KAFKA-1968
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 0.8.1.1
> Environment: javaapi on Java 6
> Reporter: Keith Bloomfield
>
> I am using a modified version of the Kafka SimpleConsumer to expose offsets
> to a rest api, based on:
> https://cwiki.apache.org/confluence/display/KAFKA/0.8.0+SimpleConsumer+Example
> However, the behavior of the example is inconsistent with the shell command:
> ./kafka-run-class.sh kafka.tools.ConsumerOffsetChecker ...
> In that sometimes it works, and sometimes it returns successfully with an
> embedded error. In other words, the check:
> if (response.hasError()) {...}
> passes because the response (as far as it's aware) has no error. But if I
> drop in a:
> response.toString().contains("error")
> then sure enough, there is an error in the response. The error is:
> kafka.common.UnknownException
> Not sure what is happening in Kafka to result in this behavior.
