Subject [jira] [Commented] (HDFS-11723) Should log a warning message when users try to make certain directories encryption zone
Date Mon, 01 May 2017 23:30:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11723?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15991782#comment-15991782

Andrew Wang commented on HDFS-11723:
------------------------------------

Thanks for the link. It's interesting that HDP recommends app data go under {{/apps/$USER}}
while CDH does {{/user/$USER}}. This would also explain why I haven't heard about this particular
trash issue for CDH users.

So, shall we pursue this as a documentation enhancement? Given that {{/user}} and etc can
be part of a valid EZ configuration, it doesn't seem appropriate to log warnings for like
this.

> If a user tries to make the entire /user directory an encryption zone, and if trash is
enabled, there will be problem when the user tries to delete unencrypted files outside /user.
The problem will happen even with the fix in HDFS-8831. So we should log a WARN message when
users try to make such directories encryption zone. Such directories include:
> {{/user}}, 
> {{/user/$user}} 
> {{/user/$user/.Trash}}
> Thanks [~xyao] for the offline discussion.
