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

```auto
esConfig:
    elasticsearch.yml: |
      bootstrap.memory_lock: true
      xpack.security.enabled: true
      xpack.ml.enabled: false
      path.data: /usr/share/elasticsearch/data0,/usr/share/elasticsearch/data1
      xpack.security.transport.ssl.enabled: true
      xpack.security.transport.ssl.verification_mode: certificate
      xpack.security.transport.ssl.keystore.path: /usr/share/elasticsearch/config/certs/elastic-certificates.p12
      xpack.security.transport.ssl.truststore.path: /usr/share/elasticsearch/config/certs/elastic-certificates.p12
readinessProbe:
  failureThreshold: 3
  initialDelaySeconds: 10
  periodSeconds: 10
  successThreshold: 3
  timeoutSeconds:  
clusterHealthCheckParams: "wait_for_status=yellow&timeout=1s"

```

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

For helm, there is a period check to curl [http://user:pwd@127.0.0.1:9200](http://user:pwd@127.0.0.1:9200), but this is failed, get error below:

Question:  
#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?
