> Components: hdfs
> Reporter: Siyao Meng

> When snapshot is disallowed on a dir, {{getTrashRoots()}} won't return the
> trash root in that dir anymore (if any). The risk is the trash root will be
> left there forever.
> We need to throw an exception there and prompt the user to clean up or rename
> the trash root if it is not empty.
