> Undefined -expunge behavior after 2.8
> -------------------------------------
>
> Key: HDFS-12484
> URL: https://issues.apache.org/jira/browse/HDFS-12484
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: fs
> Affects Versions: 2.8.0, 3.0.0-alpha1
> Reporter: Wei-Chiu Chuang
> Priority: Major
> Attachments: HDFS-12484.001.patch, HDFS-12484.002.patch

> (Rewrote the description to reflect the actual behavior)
> Hadoop 2.8 added a feature to support trash inside encryption zones, which is
> a great feature to have.
> However, when it comes to -expunge, the behavior is not well defined. A
> superuser invoking -expunge removes files under all encryption zone trash
> directory belonging to the user. On the other hand, because
> listEncryptionZones requires superuser permission, a non-privileged user
> invoking -expunge can removes under home directory, but not under encryption
> zones.
> Moreover, the command prints a scary warning message that looks annoying.
