I have a 5 machine clusters on EMR and I set up 5 NFS services.
Then I launch another EC2 machine to mount this cluster.
I find that I could mount to cluster by the physical IP address of NFS service.
But I could not mount to the cluster by the VIP.
Anyone know the reason?
I do " ifconfig" on my service machine and get the following out put
