When I try to insert 80 million nodes, it changes my LEADER and it does not insert

​I have 1 LEADER and 2 FOLLOWER, when I try to insert 80 million nodes, it changes my LEADER and it does not insert,I use the command cat ~ / persones.cypher | ./cypher-shell -u xxxxx -p xxxx -a bolt + routing: // localhost: 7787 --format plain

And my persones.cypher is:
CALL apoc.periodic.iterate('call apoc.mongodb.get("mongodb://url","DB","Collection",{}, false,0,10000000)','CREATE (a:Persona {id: value.nif}) SET a+=value', {batchSize:10000, parallel:true})
