[jira] [Created] (KAFKA-7781) Add validation check for Topic
retention.ms property

-------------------------------------------
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 [set|https://github.com/apache/kafka/blob/9295444d48eb057900ef09f1176e34b37331f60b/core/src/main/scala/kafka/server/KafkaConfig.scala#L1320] as -1.
This doesn't create any issue in log segment deletion, as the [condition|https://github.com/apache/kafka/blob/9295444d48eb057900ef09f1176e34b37331f60b/core/src/main/scala/kafka/log/Log.scala#L1466] for infinite log retention checks for value lesser than zero. To maintain consistency, we should add the validation check.
