["Jun Rao (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-1074?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13860314#comment-13860314 ] 

Jun Rao commented on KAFKA-1074:
--------------------------------

Summary of changes since the previous patch.
LogCleaner:
* moved all variables and locks associated with state management into a separate class LogCleanerStates.
* removed the semaphore for unit test and used a simpler approach to just keep retrying every 10ms. Will file a separate jira for improving the unit test.
Log:
* limited the scope of a few methods to log.
LogManager:
* forced checkpointing recovery points in truncateFullyAndStartAt() as well.
