-----------------------------------
Hi all,
Just built and tested @simplestephs proposed solution on Windows 10.
The problem persists ...
Stack trace below:

> Key: KAFKA-1194
> URL: https://issues.apache.org/jira/browse/KAFKA-1194
> Project: Kafka
> Issue Type: Bug
> Components: log
> Affects Versions: 0.10.0.0, 0.11.0.0, 1.0.0
> Environment: window
> Reporter: Tao Qin
> Priority: Critical
> Labels: features, patch, windows
> Attachments: KAFKA-1194.patch, Untitled.jpg, kafka-1194-v1.patch,
> kafka-1194-v2.patch, screenshot-1.png
>
> 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.
