Xiaoyu Yao commented on HDFS-10324: ----------------------------------- Thanks [~jojochuang] for update the patch. The patch v003 looks pretty good to me. One last comment: Do you want to update HdfsAdmin API/document for HdfsAdmin#createEncryptionZone() as well? Though I only find callers of this public API from unit tests, it seems to be a good place to implement permission change logic based on the class description below. {code} HDFSAdmin.java * The public API for performing administrative functions on HDFS. Those writing * applications against HDFS should prefer this interface to directly accessing * functionality in DistributedFileSystem or DFSClient. {code} If we decide not to change the Admin API, I still suggest an update to Javadocs of HdfsAdmin#createEncryptionZone() with the necessary permission changes for Trash of encryption zone support. > Trash directory in an encryption zone should be pre-created with sticky bit > --------------------------------------------------------------------------- > > Key: HDFS-10324 > URL: https://issues.apache.org/jira/browse/HDFS-10324 > Project: Hadoop HDFS > Issue Type: Bug > Components: encryption > Affects Versions: 2.8.0 > Environment: CDH5.7.0 > Reporter: Wei-Chiu Chuang > Assignee: Wei-Chiu Chuang > Attachments: HDFS-10324.001.patch, HDFS-10324.002.patch, > HDFS-10324.003.patch > > > We encountered a bug in HDFS-8831: > After HDFS-8831, a deleted file in an encryption zone is moved to a .Trash > subdirectory within the encryption zone. > However, if this .Trash subdirectory is not created beforehand, it will be > created and owned by the first user who deleted a file, with permission > drwx------. This creates a serious bug because any other non-privileged user > will not be able to delete any files within the encryption zone, because they > do not have the permission to move directories to the trash directory. > We should fix this bug, by pre-creating the .Trash directory with sticky bit. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
