Comments
Hey, @paymanfu welcome!🎊 Thanks for taking the time to point this out.🙌 |
for this gpdb have a better solution by higuoxing if its the same host we can skip this, also it can speed up test in local @avamingli |
Hi, @paymanfu Could you please rewrite in English so other engineers could participant, thanks! |
@yihong0618 Thanks! Your advise do save a lot of time. |
I'm not familiar with Python codes, but I believe others might be able to help. |
It's been this way forever, you need to setup some ssh keys for GP segments to communicate. Something like this works for linux:
Depending on your setup you might also But, indeed, we better just cherrypick the GP7 commit, it's a good one. |
I actually believe the user does have an ssh key created and in the proper location. The error would be different if it didn't exist. I believe the issue is that the initial host verification has not taken place. One can use ssh-keyscan to help with this. Essentially run the following replacing HOSTNAME for all hosts in the cluster. This should fix your issue:
TL;DR ssh-keyscan is a utility that helps gather the public SSH host keys of a number of hosts. How does it helps with the initial SSH connection to a system? By building .ssh/known_hosts: ssh-keyscan collects the public keys of remote hosts and adds them to the .ssh/known_hosts file. This file is used by SSH to verify the identity of the remote host, preventing man-in-the-middle attacks. |
+1, Hi, @paymanfu have you done these steps as the official doc?
In GPDB, the xxxxOS.README files are listed under the src root dir, but CBDB moved those into deep dir |

Just cherry-pick two commit refer to this. |
