Resolution: Cannot Reproduce
well, if you can't reproduce it and nobody else can, closing as a
cannot-reproduce.
if you do see it again on a recent hadoop 3.x build, reopen with stack trace

> The problem is that Hadoop tries to create fake directories to map with S3
> prefix and it cleans them after the operation. The cleaning is done from the
> parent folder until the root folder.
> If we don't give the corresponding permission for some path, it will
> encounter this problem:
> [https://github.com/apache/hadoop/blob/rel/release-2.10.0/hadoop-tools/hadoop-aws/src/main/java/org/apache/hadoop/fs/s3a/S3AFileSystem.java#L2296-L2301]
>
> During uploading, I don't see any "fake" directories are created. Why should
> we clean them if it is not really created ?
> It is the same for the other operations like rename or mkdir where the
> "deleteUnnecessaryFakeDirectories" method is called.
> Maybe the solution is to check the deleting permission before it calls the
> deleteObjects method.
>
> To reproduce the problem:
> # With a bucket named my_bucket, we have the path s3://my_bucket/a/b/c inside
> # The corresponding user has only permission on the path b and sub-path
> inside.
> # We do the command "hdfs dfs -mkdir s3://my_bucket/a/b/c/d"
