Hello Team,
Im setting up a single node cluster and below is my elasticsearch.yml file
```auto
cluster.name: my-application
node.name: node-1
node.master: true
node.data: true
bootstrap.memory_lock: true
network.host: CZASMV-MSELK004
http.port: 9200
discovery.seed_hosts: ["CZASMV-MSELK004"]
cluster.initial_master_nodes: ["CZASMV-MSELK004"]

cluster.routing.allocation.disk.threshold_enabled: false
node.max_local_storage_nodes: 3
```
Once I start the cluster, I get the WARN message telling the below
```auto
[WARN][o.e.c.c.ClusterFormationFailureHelper] [node-1] master not discovered yet, this node has not previously joined a bootstrapped (v7+) cluster, and this node must discover master-eligible nodes [CZASMV-MSELK004] to bootstrap a cluster: have discovered [{node-1}{QC2YR8ecRaWSJny4Vgr3mQ}{mpl_FOfmTJqQurBszJSwuw}{CZASMV-MSELK004}{10.200.59.35:9300}{dimr}]; discovery will continue using [] from hosts providers and [{node-1}{QC2YR8ecRaWSJny4Vgr3mQ}{mpl_FOfmTJqQurBszJSwuw}{CZASMV-MSELK004}{10.200.59.35:9300}{dimr}] from last-known cluster state; node term 0, last-accepted version 0 in term 0
```
However I can see the master role is enabled as show below
Can someone please help me if im missing something here ? Thanks for your help

Might be a good start:
```auto
discovery.seed_hosts: ['node-1', 'node-2', 'node-3']
cluster.initial_master_nodes: ['node-1', 'node-2', 'node-3']
```
