Srini commented on KAFKA-4392:
------------------------------
[~mjsax] Yes, I did set the path and can view the contents. In fact, I created
/tmp as well. The path is not the issue since java respects unix style paths on
Windows. My guess is org.apache.kafka.common.utils.Utils.delete is unable to
delete the ".lock" or ".checkpoint" file(s).
@[~habdank] Thanks, yes I am aware. Unfortunately, that will not work since we
are implementing a stateful store, 24/7 four 9s service and will need the app
to recover gracefully in case of a crash.

> This happened on streaming startup, on a clean installation, no existing
> folder. Here I was starting 4 instances of our streaming app on 4 machines
> and one threw this exception. Seems to me there’s a race condition somewhere
> when instances discover others, or something like that.
