Divij Vaidya updated KAFKA-17995:
---------------------------------
Description:
If a user has configured value of "retention.ms" to a value > current unix
timestamp epoch, then at this line of code [1] , cleanupUntilMs becomes
negative. This is because cleanupUntilMs is calculated as current unix epoch -
retention.ms [1].
This leads to cleaner failures at
[https://github.com/apache/kafka/blob/5a5239770ff3565233e5cbecf11446e76339f8fe/core/src/main/java/kafka/log/remote/RemoteLogManager.java#L2218]
and hence, all cleaning stops.
