--------------------------------------

> offsetRetentionMs miscalculated in GroupCoordinator
> ---------------------------------------------------
>
> Key: KAFKA-4472
> URL: https://issues.apache.org/jira/browse/KAFKA-4472
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.10.1.0, 0.10.0.1
> Reporter: Jason Aliyetti
> Assignee: Kim Christensen
>
> The configuration "offsets.retention.minutes" is documented as being an
> integer. When large values are set (i.e. Integer.MAX_VALUE), an overflow
> error occurs when converting from minutes to milliseconds. For instance,
> setting the config value as 2147483647 results in a offsetsRetentionMs of
> -60000. This means that all committed offsets are past their expiration when
> they are created and will be nullified on the next expiration check, which is
> unexpected given the type of the configuration.
> The fix would be to change
> "offsetsRetentionMs = config.offsetsRetentionMinutes * 60 * 1000L"
> to
> "offsetsRetentionMs = config.offsetsRetentionMinutes * 60L * 1000L"
> in GroupCoordinator.apply().
