--------------------------------------
Summary: LogCleaner CleanerStats swap logic seems incorrect
Key: KAFKA-4296
URL: https://issues.apache.org/jira/browse/KAFKA-4296
Project: Kafka
Issue Type: Bug
Reporter: Jason Gustafson
Assignee: Jason Gustafson
Fix For: 0.10.1.1
In LogCleaner, we keep track of two instances of the {{CleanerStats}} object in
a tuple object. One instance is intended to keep track the stats for the last
cycle while the other is for the current cycle. The idea is to swap them after
each cleaning cycle, but the current logic does not actually mutate the
existing tuple, which means that we always clear the same instance of
{{CleanerStats}} after each cleaning.
