Hello,

I start two local ray instances on laptop using ray.init(), running ray stop on CLI causes both the instances to shutdown. Should ray stop have an argument of head node so that we stop desired ray instances?

instance 1:

```auto
conda activate ray
(ray) $ python

>>> import ray
>>> ray.init()

```

Instance 2

```auto
$ conda activate ray

(ray) $ python

```

Running ray stop will shutdown both the cluster:

```auto
$ conda activate ray

(ray) $ ray stop

Stopped all 28 Ray processes.

```

I find another solution,just use subprocess call ray start with “–block”, and the main process watch an outside database to stop the subprocess,that will work fine
