[BUG]How to set the ip address in the cluster mode

[PaulWongDlut]

Setting: This is my first time using Mars and I face some problems maybe pretty easy for you.

I am using mars as distributed computation engine. when i set the cluster mode as the doc said. I am confused about the ip address here:

mars-worker -H -p -s : mars.new_session('http://:') (from https://mars-project.readthedocs.io/zh_CN/latest/installation/deploy.html)

Question:

1. does the ip means external network ip address or internal network?
2. I tried the external network ip address and it failed.
3. when I use the internal network ip address, and I am using VSCode on my Mac and remote-develop on a Linux system, how to open the web browser of the Mars WebUI on my Mac with the Linux internal network ip address？

Thanks for your question. The web_ip in mars.new_session('http://<web_ip>:<web_port>') is the ip address of the supervisor node. The web_port is the port you launched supervisor by setting -w. For example, we can launch a supervisor as follow:

mars-supervisor -H 11.122.207.65 -p 7001 -w 9001 -s 11.122.207.65:9001 --log-level info --log-format "%(asctime)s %(levelname)s %(filename)s:%(lineno)d - %(message)s"

11.122.207.65 is the ip address of my node. Then we can see the log:

And the 11.122.207.65:9001 is the web address.

First of all, you should ensure that the network is accessible, if you want to access the Mars Web service in your remote Linux. You can verify this by ping or telnet.

I don't understand your external network ip and internal network ip. You can execute the python code in your remote Linux to ensure the Mars is launched or not.
