Summary: Add validation check for Topic retention.ms property
Key: KAFKA-7781
URL: https://issues.apache.org/jira/browse/KAFKA-7781
Project: Kafka
Issue Type: Bug
Reporter: Kamal Chandraprakash
Using AdminClient#alterConfigs, topic _retention.ms_ property can be assigned
to a value lesser than -1. This leads to inconsistency while describing the
topic configuration. We should not allow values lesser than -1. In
server.properties, if _log.retention.ms_ configured to a value lesser than
zero, it's

as -1.
This doesn't create any issue in log segment deletion, as the

for infinite log retention checks for value lesser than zero. To maintain
consistency, we should add the validation check.
