--------------------------------

             Summary: Implement a getTrashRoot that does not fall-back
                 Key: HDFS-11091
                 URL: https://issues.apache.org/jira/browse/HDFS-11091
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.8.0
            Reporter: Xiao Chen


From HDFS-10756's [discussion|https://issues.apache.org/jira/browse/HDFS-10756?focusedCommentId=15623755&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15623755]:
{{getTrashRoot}} is supposed to return the trash dir considering encryption zone. But if there's an error encountered (e.g. access control exception), it falls back to the default trash dir.

Although there is a warning message about this, it is still a somewhat surprising behavior. The fall back was added by HDFS-9799 for compatibility reasons. This jira is to propose we add a getTrashRoot that throws, which will actually be more user-friendly.
