[jira] [Commented] (KAFKA-209) Remove empty directory when no log segments remain

    [ https://issues.apache.org/jira/browse/KAFKA-209?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13153918#comment-13153918 ] 

Jun Rao commented on KAFKA-209:
-------------------------------

Actually, when all log segments are deleted, we automatically create an empty log file whose name is the latest offset. So the log directory will never be empty.

> When the log cleaner runs it deletes segments from the log directory.  However, if all the segments are cleaned, the log directory itself is retained.  There doesn't seem to be any need for this as the directory will be re-created on write if necessary.
> This JIRA would improve the log cleaner to also remove unused topic directories from the log directory.
