Subject [jira] [Updated] (HDFS-12484) hdfs dfs -expunge requires superuser permission after 2.8
Date Mon, 18 Sep 2017 22:49:00 GMT

     [ https://issues.apache.org/jira/browse/HDFS-12484?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Wei-Chiu Chuang updated HDFS-12484:
-----------------------------------
    Description: 
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.
