Dong Lin commented on KAFKA-6188:
---------------------------------

[~manme...@gmail.com] Thanks for your detailed information. Sorry for late 
reply. I was not monitoring this Jira ticket discussion. My understanding of 
your comment is that FIleSystemException is expected if Kafka tries to 
delete/rename a file which is already open. I checked the current logic in the 
Kafka 1.1.0 code. For log compacted topic, `replaceSegments()` will be called 
which in turn calls `asyncDeleteSegment()` and `segment.changeFileSuffixes`. 
Similarly for non-log-compacted topics, `deleteSegment()` calls 
`asyncDeleteSegment()` which also modified file without first closing the file. 
So it should affect every user constantly if this is an issue, right?

Given that this does not happen in Linux machine at LinkedIn, this issue seems 
to be specific Windows or NAS which requires user to close the file before 
modifying the file. Does this make sense?

> Just started with version 1.0.0 after a 4-5 months of using 0.10.2.1. The 
> test environment is very simple, with only one producer and one consumer. 
> Initially, everything started fine, stand alone tests worked as expected. 
> However, running my code, Kafka clients fail after approximately 10 minutes. 
> Kafka won't start after that and it fails with the same error. 
> Deleting logs helps to start again, and the same problem occurs.
