Description

This issue came out of a discussion on the user mailing list (not something I experienced directly).

Bob Cotton reported:
"During the implementation of a custom Encoder/Decoder we noticed that
should the Decoder throw an exception, the KafkaStream that it is in use
becomes invalid.

Searching the mailing list indicates that the only way to recover from an
invalid stream is to shutdown the whole high-level consumer and restart.

Is there a better way to recover from this?

Thanks for the responsiveness on the mailing list."

And then Neha responded:

"This is a bug. Ideally, we should allow restarting the consumer
streams when they encounter an error.
Can you file a JIRA ?

Thanks,
Neha"
