-----------------------------------------------------------------
This issue was already addressed in FLINK-8373. But it's not addressed properly:
Creating an empty directory and checking for existence does not work in the
presto implementation. See corresponding
[FileSystemBehaviorTestSuite:125|https://github.com/apache/flink/blob/c6997c97c575d334679915c328792b8a3067cfb5/flink-core/src/test/java/org/apache/flink/core/fs/FileSystemBehaviorTestSuite.java#L125]
where this specific behavior is excluded.
We might want to fix that properly since it's an easy-to-fall-into trap

> FileSystem.getFileStatus fails for directories

> Key: FLINK-26061
> URL: https://issues.apache.org/jira/browse/FLINK-26061
> Project: Flink
> Issue Type: Technical Debt
> Components: Connectors / FileSystem
> Affects Versions: 1.15.0
> Reporter: Matthias Pohl
> Priority: Major
>
> {{FileSystem.getFileStatus}} is not supported for directories in object
> stores (like s3). We might want to adjust the interface here. It's not clear
> based on the contract that for certain {{FileSystem}} implementations. This
> is especially unintuitive because there is a {{isDir()}} method provided by
> the resulting {{FileStatus}} instance.
