Wei-Chiu Chuang commented on HDFS-10324:
----------------------------------------
Thanks [~xyao] for the comments. Regarding #1, I don't have a strong opinion
whether to keep it configurable or not.
I am not so sure about #2 though. Essentially, adding a trash directory is
equivalent to {{hdfs dfs -mkdir /ez/tmp; hdfs dfs -chmod 1777 /ez/tmp}}, and an
extra command seems redundant to me. But if this command is designed to handled
more complex cases, then I am certainly open to that.

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