Copying from the root to a subdirectory should be forbidden

      Description

      HDFS forbids copying from a directory to its subdirectory (e.g. hdfs dfs -cp /abc /abc/xyz) as otherwise it could cause infinite copying (/abc/xyz/xyz, /abc/xyz/xyz, /abc/xyz/xyz/xyz,... etc)

      However, the existing path validation fails if the source path is the root, causing infinite copying, until the disk space is filled up.
