[jira] [Commented] (KAFKA-888) problems when shutting down the java consumer .

    [ https://issues.apache.org/jira/browse/KAFKA-888?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13644929#comment-13644929 ]

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
