hadoop - localhost：权限被拒绝（公钥，密码）

问题描述

我有 hadoop 3.0.0 独立在 Ubuntu 16.04 上工作并转换为 Suedo 分布式并处于使用命令运行主节点和从节点的阶段

$ sudo /usr/local/hadoop/sbin/start-dfs.sh

结果显示为

[sudo] password for tc: 
/usr/local/hadoop/etc/hadoop/hadoop-env.sh: line 1: #: command not found
WARNING: HADOOP_SECURE_DN_USER has been replaced by HDFS_DATANODE_SECURE_USER. Using value of HADOOP_SECURE_DN_USER.

我不明白为什么它会说；

localhost：权限被拒绝（公钥，密码）。

当我输入我的 root 用户密码时，
我将 hadoop-env.sh 设置为；

export HDFS_DATANODE_USER=root
export HADOOP_SECURE_DN_USER=hdfs 
export HDFS_NAMENODE_USER=root 
export HDFS_SECONDARYNAMENODE_USER=root

有人能告诉我为什么我会收到这条消息吗？

localhost：权限被拒绝（公钥，密码）。

我应该关心

hadoop-env.sh：第 1 行：#：找不到命令
