Generally all processors are executing within a single OS process started by a single user. The only case I can think of where one processor could execute at a higher level would be when using the ExecuteProcess/ExcuteStreamCommand processors... the command can be "sudo" and the args can be the command to execute. This assumes the user that started NiFi has sudo privileges.
