> Project: Kafka
> Issue Type: Bug
> Components: log
> Affects Versions: 0.8.1
> Environment: window
> Reporter: Tao Qin
> Assignee: Jay Kreps
> Labels: features, patch
> Fix For: 0.10.2.0
>
> Attachments: KAFKA-1194.patch, Untitled.jpg, kafka-1194-v1.patch,

> Original Estimate: 72h
> Remaining Estimate: 72h
>
> We tested it in windows environment, and set the log.retention.hours to 24
> hours.
> # The minimum age of a log file to be eligible for deletion
> log.retention.hours=24
> After several days, the kafka broker still cannot delete the old log file.
> And we get the following exceptions:

> I think this error happens because kafka tries to rename the log file when it
> is still opened. So we should close the file first before rename.
> The index file uses a special data structure, the MappedByteBuffer. Javadoc
> describes it as:
> A mapped byte buffer and the file mapping that it represents remain valid
> until the buffer itself is garbage-collected.
> Fortunately, I find a forceUnmap function in kafka code, and perhaps it can
> be used to free the MappedByteBuffer.
