Using a Local User for NiFi Windows Service
There is no prerequisite to use a Local user for the Windows service. The installer automatically sets up the user.
If the computer is a part of a domain, then Local User checkbox appears in the HDF NiFi setup window. Check the Local User checkbox to specify that Local user is used to execute the installed service.
If a user specified at NiFi service username does not exist, the installer creates one with the specified NiFi service password. If the user already exists, the installer updates its password with the specified password.
The installer also grants the following privileges to the specified user:
SeCreateSymbolicLinkPrivilege
SeServiceLogonRight
