If you did not set the config, the default will be used.
For your version of Kafka (0.10.2.1) the default is 1 day:

Subject: Re: Question how to drop a unused group id?
Ok, thanks again for the help, and another question, by default we did not
set the config item, so does not it take effect with the default
situation?
I just searched the code with the configuration key “
offset.retention.minutes", but I can get any reference, be changed?

Hi Peyton,
Yes, if you'd like to change the value a broker restart is required for
the change to take effect.

Hi Vahid,
Thank you very much for the reply, we use the kafka ver 2.11-0.10.2.1.
So when I apply the "offset.retention.minutes" to the system that request
a restart to be effected?

Hi Peyton,
What version of Kafka are you using?
Starting from version 1.1.0 there is a DELETE_GROUP API:
https://cwiki.apache.org/confluence/display/KAFKA/KIP-229%3A+DeleteGroups+API
You can also use the consumer group command with `--delete` to delete a
group.
For prior versions, the safest option would be to wait for
`offset.retention.minutes` until all group offsets are expired.
