Re: Unable to reset kafka offset in a consumer group

[Chris Peart <ch...@peart.me.uk>]

Hi Luke,

I could not get the consumer group to be inactive even when stopping all 
the consumers in the group.

Due this this being a production system i was unable to play to much 
with the kafka-consumer-groups --reset-offsets --shift-by command, so i 
had to run the following command:

kafka-run-class kafka.tools.UpdateOffsetsInZK latest (properties file 
containing kafka brokers) topicname

After doing this i consumed the missing offsets to file and the used 
kafka-producer to read from the file to the affected topic.

Hope this makes sense, i know there are better probably ways to do this 
but needed a quick and dirty fix :)

Thanks,

Chris
