Unable to create ring in DS201 Exercise 7 on local Mac
This issue has been reported previously in #6307. I'll repost some of the details here.
I've tried this on various machines with no success on replicating it:
- Macbook Pro 16" running macOS Catalina
- Macbook 12" running macOS High Sierra
- Surface Pro 7 running Windows 10
- Surface Laptop 3 running Windows 10
In multiple tests that I ran with VirtualBox using the Academy VM image for DS201 and following the instructions in exercise 7, I was able to successfully get both node1 and node2 running. In all instances, I can see that the internode port 8609 is bound to 127.0.0.2:
$ sudo lsof -nPi -sTCP:LISTEN COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME sshd 789 root 3u IPv4 14038 0t0 TCP *:22 (LISTEN) sshd 789 root 4u IPv6 14051 0t0 TCP *:22 (LISTEN) java 2177 ubuntu 489u IPv4 19693 0t0 TCP 127.0.0.1:8609 (LISTEN) java 2177 ubuntu 491u IPv4 19698 0t0 TCP 127.0.0.1:42913 (LISTEN) java 2177 ubuntu 492u IPv4 19699 0t0 TCP *:7199 (LISTEN) java 2177 ubuntu 496u IPv4 20981 0t0 TCP 127.0.0.1:9041 (LISTEN) java 2177 ubuntu 500u IPv4 20202 0t0 TCP 127.0.0.1:7000 (LISTEN) java 2816 ubuntu 489u IPv4 25732 0t0 TCP 127.0.0.2:8609 (LISTEN) java 2816 ubuntu 491u IPv4 25744 0t0 TCP 127.0.0.1:39882 (LISTEN) java 2816 ubuntu 492u IPv4 25747 0t0 TCP *:7299 (LISTEN) java 2816 ubuntu 496u IPv4 27026 0t0 TCP 127.0.0.1:9042 (LISTEN) java 2816 ubuntu 500u IPv4 26326 0t0 TCP 127.0.0.2:7000 (LISTEN)
Specifically:
java 2816 ubuntu 489u IPv4 25732 0t0 TCP 127.0.0.2:8609 (LISTEN)
The only other time I've seen this happen is when VirtualBox itself (not DSE) is not configured correctly and is suffering from a networking issue.
Make sure you don't have VPN enabled or special networking configured on your machine that could be conflicting with the VM.
The only other suggestion I have is that you reboot your Mac and delete the VM in VirtualBox and start again. Cheers!
Right, but the analysis is still the same -- the process can't bind to 127.0.0.2. It's a networking issue, not DSE.
You need to configure DSE with an IP that is accessible on your mac.Cheers!
