> FileBaseUtils#deleteFileOrDirectory not thread-safe on Windows
> --------------------------------------------------------------
>
> Key: FLINK-5659
> URL: https://issues.apache.org/jira/browse/FLINK-5659
> Project: Flink
> Issue Type: Bug
> Components: Core, Local Runtime
> Affects Versions: 1.2.0, 1.3.0, 1.4.0
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Trivial
>
> The {code}FileBaseUtils#deleteFileOrDirectory{code} is not thread-safe on
> Windows.
> First you will run into AccessDeniedExceptions since one thread tried to
> delete a file while another thread was already doing that, for which the file
> has to be opened.
> Once you resolve those exceptions (by catching them double checking whether
> the file still exists), you run into DirectoryNotEmptyExceptions since there
> is some wacky timing/visibility issue when deleting files concurrently.
