When I close master node,is this situation right?

My environment: elasticsearch-7.4.2 node-1,node-2(two nodes,and node-2 is the master node)

When I closed the node-2 ,which is the master node, the node-1 begin to find the master node and show like this:

[node-1] master not discovered or elected yet, an election requires a node with id [eUfWAIhSQzCRcisWz-DiFg], have discovered [{node-1}{WbYI8RHITU2aJYMMoD-ZXw}{0iKKLbdeQ3mmWNKo7iKkOg}{}{}{dim}{rack=r1, xpack.installed=true}] which is not a quorum; discovery will continue using [] from hosts providers and [{node-1}{WbYI8RHITU2aJYMMoD-ZXw}{0iKKLbdeQ3mmWNKo7iKkOg}{}{}{dim}{rack=r1, xpack.installed=true}] from last-known cluster state; node term 5, last-accepted version 245 in term 5

I just want to know the reason is avoiding Cerebral fissure or not?

thanks bro
