RAY Java init error

How severe does this issue affect your experience of using Ray?

  • High: It blocks me to complete my task.

Hi RAY team, recently I’ve ran into a problem that I can’t start a ray instance from Java code, and I later noticed that in Ray.init() method, the framework will automatically set the redis password to a fixed random number. I’ve tried to set the redis-password from System.property, or from ray.conf file, neither of them worked.
I’ve read an article that said RAY in Java couldn’t be started with code, it could only be connected to an already running instance? Is this real? But why is there a Ray.init() method?
So, is there any other method or am i doing it incorrectly? I also notice that there are so little tutorials or docs about using RAY in Java. But what I’m working around is a project that needs cross language programming.
Please, if you have time, answer my questions, I know the problems may be a little stupid but I’m just a newbie using this framework.
