• Type: Bug
• Status: Resolved
• Priority: Major
• Resolution: Fixed

Release Note

If root path / is an encryption zone, the old DistributedFileSystem#getTrashRoot(new Path("/")) returns
/user/$USER/.Trash
which is a wrong behavior. The correct value should be
/.Trash/$USER

Description

Let's say root path ("/") is the encryption zone, and there is a file called "/test" in root path.

dfs.getTrashRoot(new Path("/"))

returns "/user/$USER/.Trash",
while

dfs.getTrashRoot(new Path("/test"))

returns "/.Trash/$USER".
The first behavior is not correct. Since root path is the encryption zone, it's more reasonable to return "/.Trash/$USER" no matter what the path is.
