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

             Summary: rename operation should check nest snapshot
                 Key: HDFS-14925
                 URL: https://issues.apache.org/jira/browse/HDFS-14925
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
            Reporter: Junwang Zhao


When we do rename operation, If the src directory or any of its descendant

is snapshottable and the dst directory or any of its ancestors is snapshottable, 

we consider this as nested snapshot, which should be denied.
