Xiaoyu Yao commented on HDDS-3171:
----------------------------------

I think this is related to the K8s environment where the name resolution is 
unreliable for scm host when om rpc client is making the call. you might want 
to take a look at the K8s node logs like mentioned here: 
https://github.com/kubernetes/kubernetes/issues/76790.




> Couldn't create RpcClient protocol exception on k8s.
