>                 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])
