Jun Rao commented on KAFKA-888:
-------------------------------
This logging itself is ok. We interrupt the fetcher thread when shutting down
the consumer. Other than the logging, could your consumer shutdown? Also,
normally, you iterate and consume messages in a separate thread. See the
example in
https://cwiki.apache.org/confluence/display/KAFKA/Consumer+Group+Example
> problems when shutting down the java consumer .
