      Description

      When some dfs operations fail due to SnapshotAccessControlException, valid exit codes are not returned.

      E.g:

      -bash-4.1$  hadoop dfs -chmod -R 755 /user/foo/hdfs-snapshots/test0/.snapshot/s0
      chmod: changing permissions of 'hdfs://<namenode>:8020/user/foo/hdfs-snapshots/test0/.snapshot/s0':org.apache.hadoop.hdfs.server.namenode.snapshot.SnapshotAccessControlException: Modification on read-only snapshot is disallowed
      
      -bash-4.1$ echo $?
      0
      
      -bash-4.1$  hadoop dfs -chown -R hdfs:users /user/foo/hdfs-snapshots/test0/.snapshot/s0
      chown: changing ownership of 'hdfs://<namenode>:8020/user/foo/hdfs-snapshots/test0/.snapshot/s0':org.apache.hadoop.hdfs.server.namenode.snapshot.SnapshotAccessControlException: Modification on read-only snapshot is disallowed
      
      -bash-4.1$ echo $?
      0
      

      Similar problems exist for some other exceptions such as SafeModeException.
