Wei-Chiu Chuang created HDFS-12484:
--------------------------------------
Summary: hdfs dfs -expunge requires superuser permission 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: 3.0.0-alpha1, 2.8.0
Reporter: Wei-Chiu Chuang
Assignee: Wei-Chiu Chuang
Hadoop 2.8 added a feature to support trash inside encryption zones.
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.
