Question

我有独立的hadoop 3.0.0在Ubuntu 16.04上运行并转换为Suedo分布式，并且在使用命令运行Master和salve Nodes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WARNING: HADOOP_SECURE_DN_USER has been replaced by HDFS_DATANODE_SECURE_USER.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.

我无法理解为什么要说出来;

localhost：权限被拒绝（公钥，密码）。

当我输入root用户密码时我已将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

有人可以告诉我为什么我收到此消息？

localhost：权限被拒绝（公钥，密码）。

我应该关注

hadoop-env.sh：第1行：＃：未找到命令

localhost：权限被拒绝（公钥，密码）
