-------------------------------------
Summary: offsetRetentionMs miscalculated in GroupCoordinator
Key: KAFKA-4472
URL: https://issues.apache.org/jira/browse/KAFKA-4472
Project: Kafka
Issue Type: Bug
Affects Versions: 0.10.0.1, 0.10.1.0
Reporter: Jason Aliyetti
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().
