Hi, We are facing some issues while upgrading ES from 5.5.2 -> 7.8.1. We have two nodes deployment setup. ES is installed in both nodes and both are master eligible. In earlier version we used to have two master nodes. When one node goes down, and the other node chosen to be a master automatical…

Is there a way to choose the other master eligible node as master automatically if the elected master node goes down (in unexpected sceanrio's)?

For a cluster to be highly available you need at least three master eligible nodes. With just two nodes any node failure will result in no master being elected, which is the correct behaviour.
