huxihx updated KAFKA-9322:
--------------------------
Description: When debugging, it will be convenient to quickly check the
last N messages for a partition using ConsoleConsumer. Currently `offset` could
not be negative except -1 and -2. However, we could simply break this rule to
support `tail -n` feature. A tricky thing is currently we treat -1 and -2 as
special values, so I am not sure if a new KIP is needed. (was: When debugging,
