Node not join the cluster so what happen about the data?

I found problem that one node can see all 4 node but another node cannot
see this node like the head page.

The number of the data is not equals between them. Can I restore all the
data?

All the nodes can probably see each other, your issue is that you have a
split-brain, probably caused when one of the nodes was momentarily
unresponsive (> timeout). You have two clusters with two separate master
nodes. I would try restarting Blind Justice (xxx.xxx.xxx.208). Your data
appears to be intact, however you will have duplicate data. After the
cluster has reformed, look into your path.data directory for two nodes
(nodes/0 and nodes/1) and delete the one not being updated.

You should set discovery.zen.minimum_master_nodes to 3 (4/2+1), but that
still does not ensure split brain will not happen when a node is removed.

For my own knowledge why it does not ensure split brain will not happen ?
