Matthias Pohl commented on FLINK-26484:
---------------------------------------
We should implement the recursive deletion in {{FileSystem}} and only rely on
{{FileSystem.deleteFile(path)}} (which is a replacement for
{{FileSystem.delete(path, false)}}), {{FileSystem.exists(path)}}, and
{{FileSystem.listStatuses(path)}}. We can remove redundant code in
{{LocalFileSystem}} as well due to that.
> FileSystem.delete is not implemented consistently

> Key: FLINK-26484
> URL: https://issues.apache.org/jira/browse/FLINK-26484
> Project: Flink
> Issue Type: Bug
> Components: Connectors / FileSystem, Runtime / Coordination
> Affects Versions: 1.15.0
> Reporter: Matthias Pohl
> Priority: Critical
>
> The BlobServer cleanup does not work for the Presto S3 filesystem in case of
> failure due to some bug in the recursive delete implementation. The {{false}}
> return value is not processed which leads to an error case being "swallowed",
> i.e. recursive cleanups do not work in this case (see
> [PrestoS3FileSystem:496|https://github.com/prestodb/presto/blob/master/presto-hive/src/main/java/com/facebook/presto/hive/s3/PrestoS3FileSystem.java#L496])
