             Summary: Should log a warning message when users try to make certain directories encryption zone
                 Key: HDFS-11723
                 URL: https://issues.apache.org/jira/browse/HDFS-11723
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: encryption, hdfs-client
            Reporter: Chen Liang
            Assignee: Chen Liang


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 file from /user to trash directory. 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.
