Yuanbo Liu updated HDFS-10883:
------------------------------
Release Note:
<!-- markdown -->
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
```
was:
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
> `getTrashRoot`'s behavior is not consistent in DFS after enabling EZ.

> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Yuanbo Liu

>
> Attachments: HDFS-10883-test-case.txt, HDFS-10883.001.patch,

> 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 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.
