> We do. The Presto S3 Filesystem requires it. That's what [FLINK-26061](https://issues.apache.org/jira/browse/FLINK-26061) is about. I'm wondering if that isn't yet again a minio issue. From everything I have read presto assumes that everything is an empty directory by default (hence why mkdirs doesn't do anything). So unless you check that a directory does _not_ exist things should be fine. https://hadoop.apache.org/docs/stable/hadoop-aws/tools/hadoop-aws/directory_markers.html Did you step through PrestoS3FileSystem to see which call fails? How does the test (FileSystemBehaviorTestSuite.testMkdirsCreatesParentDirectories) actually fail? Is the assertion failing, or is the FS throwing a FileNotFoundException. I'm asking because FileSystem#exists only checks whether getFileStatus returns null, but I don't see a codepath in the presto filesystem where that can be the case. -- This is an automated message from the Apache Git Service.
