>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: fs
>    Affects Versions: 3.0.0-alpha1, 2.8.0
>            Reporter: Wei-Chiu Chuang

> Hadoop 2.8 added a feature to support trash inside encryption zones, which is a great
feature to have.
> However, it breaks the existing -expunge semantics because now a user must have superuser
permission in order to -expunge. The reason behind that is that -expunge gets all encryption
zone paths using DFSClient#listEncryptionZones, which requires super user permission.
> Not sure what's the best way to address this, so file this jira to invite comments.
