Steve Loughran commented on HDFS-16032:
---------------------------------------
FYI this would
# destroy performance on s3a, where copy is used on rename
# make delete faster on abfs where oauth is used to authenticate, as there a
delete() call forces a treewalk of all directories to validate caller has the
permissions it needs. HADOOP-17691. But when ABFS starts throttling, renames()
may fail in ways that delete doesn't.
we are discussing adding a plugin point for per-schema trash: HADOOP-18013
it would be possible to add something in FileUtils to use this, but
FileSystem.delete() *must not* suddenly move things to trash.
> DFSClient#delete supports Trash
