Master node failed to retrieve password

I have use helm to deploy a cluster with 3 master node + 4 data node.
Master node part of config:

    elasticsearch.yml: |
      bootstrap.memory_lock: true true false /usr/share/elasticsearch/data0,/usr/share/elasticsearch/data1 true certificate /usr/share/elasticsearch/config/certs/elastic-certificates.p12 /usr/share/elasticsearch/config/certs/elastic-certificates.p12
  failureThreshold: 3
  initialDelaySeconds: 10
  periodSeconds: 10
  successThreshold: 3
clusterHealthCheckParams: "wait_for_status=yellow&timeout=1s"

I have updated [] from [100%] to [80%]
Then the data node got this error, and 3 data node become unready cause the readinessProbe check failed.

{"type": "server", "timestamp": "2021-08-03T11:01:31,671Z", "level": "WARN", "component": "o.e.x.m.e.l.LocalExporter", "": "insight", "": "insight-master-0", "message": "unexpected error while indexing monitoring document", "cluster.uuid": "wzBzIPDTQ4KW7IGMMxDuug", "": "q_3QuVnHTbmC6mbIvoX9rQ" ,

For helm, there is a period check to curl http://user:pwd@, but this is failed, get error below:

{"type": "server", "timestamp": "2021-08-03T11:19:15,212Z", "level": "ERROR", "component": "o.e.x.s.a.e.ReservedRealm", "": "insight", "": "insight-master-0", "message": "failed to retrieve password hash for reserved user [elastic]", "cluster.uuid": "wzBzIPDTQ4KW7IGMMxDuug", "": "q_3QuVnHTbmC6mbIvoX9rQ","stacktrace": ["org.elasticsearch.transport.RemoteTransportException: [insight-data-0][][indices:data/read/get[s]]"

#1 What data do master node store, will it store the security data, like password for elastic?
#2 Why get this error, it will connect to data node to check the authority?
