Subject [jira] [Commented] (KAFKA-3408) consumer rebalance fail
Date Fri, 12 Aug 2016 17:23:20 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-3408?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15419157#comment-15419157

Dru P commented on KAFKA-3408:

[~sdhzlzhk] The information you've provided is insufficient to reproduce the issue. 

/bin/kafka-console-consumer starts the old consumer whose default value for 'rebalance.max.retries'
is 4 and yet your stacktrace prints 'can't rebalance after 10 retries', something is off here..

I need the following details:

# Is this an actual failure which leaves your Kafka broker + clients useless or does the consumer
eventually recover from the rebalance failure?
# The exact command used to start the two consumers (any specific config in your CLI args)
# Number of partitions of the topic?
# Any config changes
