When running the Kafka 0.8.2-Beta (Scala 2.10) on Windows, an attempt to delete
the Topic throwed an error:
ERROR [KafkaApi-1] error when handling request Name: StopReplicaRequest;
Version: 0; CorrelationId: 38; ClientId: ; DeletePartitions: true;
ControllerId: 0; ControllerEpoch: 3; Partitions: [test,0]

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...
