假設使用者名是 username，方案有兩種
方式一：修改sudoers檔案
sudo gedit /etc/sudoers
把root那行複制後改成hadoop，hadoop就有了sudo權限，需要sudo密碼則為ALL，不需要則NOPASSWD:ALL。
#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults env_reset
Defaults mail_badpass
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"
# Host alias specification
# User alias specification
# Cmnd alias specification
# User privilege specification
root ALL=(ALL:ALL) ALL
username ALL=(ALL) ALL
# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL
# Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL
# See sudoers(5) for more information on "#include" directives:
#includedir /etc/sudoers.d
方式二：還是修改sudoers配置檔案，認真分析你會發現
## Uncomment to allow members of group sudo to execute any command
%sudoALL=(ALL) ALL
允許sudo組的使用者執行sudo，那把普通使用者添加到sudo組裡頭不就行了
usermod -a -G sudo username
附：要是報告不存在sudo組，就先增加sudo組
groupadd sudo
