Subject [jira] [Created] (HDFS-10324) Trash directory in an encryption zone should be pre-created with sticky bit
Date Fri, 22 Apr 2016 06:22:12 GMT
Wei-Chiu Chuang created HDFS-10324:
--------------------------------------

             Summary: 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


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 within the trash directory.

We should fix this bug, by pre-creating the .Trash directory with sticky bit.
