Yuanbo Liu updated HDFS-10883:
------------------------------
Release Note:
If root path {{/}} is an encryption zone, the old
{{DistributedFileSystem#getTrashRoot(new Path("/"))}} returns
{code}
/user/$USER/.Trash
{code}
which is a wrong behavior.
The correct value should be
{code}
/.Trash/$USER
{code}
Description:
Let's say root path ("/") is the encryption zone, and there is a file called
"/test" in root path.
{code}
dfs.getTrashRoot(new Path("/"))
{code}
returns "/user/$USER/.Trash",
while
{code}
dfs.getTrashRoot(new Path("/test"))
{code}
returns "/.Trash/$USER".
The second behavior is not correct. Since root path is the encryption zone,
which means all files/directories in DFS are encrypted, it's more reasonable to
return "/.Trash/$USER" no matter what the path is.
