{quote}TrashOzoneFileSystem#getTrashRoots should support Ozone, S3A (HDFS
trash), and currently HDFS trash before HADOOP-19217.

I feel we need to somehow get the client FS to move to the correct place for
ozone if the underlying store is Ozone. Solving this at the server by adding
numerous paths that are implemented by various FS paths is not a good design
IMO. This can lead to bugs which can wrongfully delete a key leading to data
loss.

> Key: HDDS-13806
> URL: https://issues.apache.org/jira/browse/HDDS-13806
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Sammi Chen
> Priority: Major
>
> When trash is enabled and user deletes a Ozone file through s3a:// schema,
> the file will be moved to HDFS default trash root, instead of Ozone default
> trash root. Since the trash deletion thread in Ozone only checks Ozone
> default trash root, so these files deleted through s3a:// will never get a
> chance to be deleted.
> HDFS trash behaivor:
> * For unencrypted files, the HDFS trash root is typically located in the
> user's home directory under /user/<username>/.Trash, where deleted files are
> moved to /user/<username>/.Trash/Current/OriginalPath.
> * For encrypted files, the trash root is within the encryption zone's root
> directory at /EncryptionZoneRoot/.Trash, and files are moved to
> /EncryptionZoneRoot/.Trash/$USER/Current/OriginalPath. The trash can be
> accessed using hdfs dfs -ls /user/<username>/.Trash or by using a path
> prefixed with hdfs://
> Ozone trash behavior:
> In Apache Ozone, the default trash location for keys in a File System
> Optimized (FSO) bucket is within the bucket itself. The specific path
> is:/<volume>/<bucket>/.Trash/<user>, where deleted files are moved to
> /<volume>/<bucket>/.Trash/<user>/Current/OriginalPath
> The problem is found by [~chenxi]
