> When I have investigated the issue I figured out that the index file (in my environment
it was C:\tmp\kafka-logs\00000000-0000-0000-0000-000000000014-0\00000000000000000000.index)
was locked by the kafka process and the OS did not allow to delete that file.
> I tried to fix the problem in source codes and when I added close() method call into
LogSegment.delete(), the Topic deletion started to work.
> I will add here (not sure how to upload the file during issue creation) a diff with the
changes I have made so You can take a look on that whether it is reasonable or not. It would
be perfect if it could make it into the product...
> In the end I would like to say that on Linux the deletion works just fine...
