Wei-Chiu Chuang reassigned HDFS-12484: -------------------------------------- Assignee: (was: Wei-Chiu Chuang) > 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. > {noformat} > 2017-09-21 01:22:44,744 [main] WARN hdfs.DFSClient > (DistributedFileSystem.java:getTrashRoots(2795)) - Cannot get all encrypted > trash roots > org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException): > Access denied for user user.
