> Hi,
> if I specify the --partition option for the console consumer with a not
> existing partition for a topic, the application hangs indefinitely.
> Debugging the code I see that it asks for metadata but when it receives topic
> information and it doesn't find the requested partition inside such metadata,
> the code retries new time.
> Could be it worst to check if the partition exists using the partitionFor
> method before calling the assign in the seek of the BaseConsumer and throwing
> an exception so printing an error on the console ?
> Thanks,
> Paolo
