Maybe the new method shoud be added to org.apache.hadoop.fs.Trash :
{code:java}
// code placeholder
public static boolean moveToAppropriateTrash(FileSystem fs, Path p,
Configuration conf,String user) throws IOException, InterruptedException {
Path fullyResolvedPath = fs.resolvePath(p);
// Get FileSystem by user.
FileSystem fullyResolvedFs =
FileSystem.get(fullyResolvedPath.toUri(), conf, user);
// If the trash interval is configured server side then clobber this
// configuration so that we always respect the server configuration.
try {
long trashInterval = fullyResolvedFs.getServerDefaults(
fullyResolvedPath).getTrashInterval();
if (0 != trashInterval) {
Configuration confCopy = new Configuration(conf);
confCopy.setLong(CommonConfigurationKeysPublic.FS_TRASH_INTERVAL_KEY,
trashInterval);
conf = confCopy;
}
} catch (Exception e) {
// If we can not determine that trash is enabled server side then
// bail rather than potentially deleting a file when trash is enabled.
LOG.warn("Failed to get server trash configuration", e);
throw new IOException("Failed to get server trash configuration", e);
}
Trash trash = new Trash(fullyResolvedFs, conf);
boolean success = trash.moveToTrash(fullyResolvedPath);
if (success) {
System.out.println("Moved: '" + p + "' to trash at: " +
trash.getCurrentTrashDir() );
}
return success;
}
{code}

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client
>Affects Versions: 2.10.0, 3.3.1
>Reporter: Vince.Feng
>Priority: Minor
>
> When HDFS client with viewfs want to move file/directory to trash by
> RemoteUser or
> ProxyUser , it will fail. Codes like below:
> {code:java}
> // code placeholder
> Trash.moveToAppropriateTrash(fileSystem, path, conf);
> {code}
>
>
> 'fullyResolvedFs' will return a FileSystem with ugi of system user. But the
> source fileSystem ugi was specified account. So the moving to trash operation
> will fail. Because of trashRoot mismatch the real baseTrashPath.
