Добрый день!

Собираю новый кластер (3 мастера, 5 дата-нод.) Один из мастеров не может подключиться. Вижу такую ошибку в его логе:

```auto
[2020-06-16T14:01:49,770][WARN][o.e.c.c.ClusterFormationFailureHelper] [wss-es-master1a.blabla.ru] master not discovered yet, this node has not previously joined a bootstrapped (v7+) cluster, and this node must discover master-eligible nodes [wss-es-master1a.blabla.ru, wss-es-master2a.blabla.ru, wss-es-master3a.blabla.ru] to bootstrap a cluster: have discovered [{wss-es-master1a.blabla.ru}{ygcUhMmtRTSIyzZI3hlcGA}{77wzzsbXTUyW8LWUD5gLrQ}{wss-es-master1a.blabla.ru}{192.168.50.104:9300}{lmr}{ml.machine_memory=8370466816, xpack.installed=true, transform.node=false, ml.max_open_jobs=20}]; discovery will continue using [192.168.50.194:9300, 192.168.48.118:9300, 192.168.51.37:9300, 192.168.50.69:9300, 192.168.48.215:9300, 192.168.48.171:9300, 192.168.48.250:9300] from hosts providers and [{wss-es-master1a.blabla.ru}{ygcUhMmtRTSIyzZI3hlcGA}{77wzzsbXTUyW8LWUD5gLrQ}{wss-es-master1a.blabla.ru}{192.168.50.104:9300}{lmr}{ml.machine_memory=8370466816, xpack.installed=true, transform.node=false, ml.max_open_jobs=20}] from last-known cluster state; node term 0, last-accepted version 0 in term 0

```

Судя по [документации](https://www.elastic.co/guide/en/elasticsearch/reference/master/modules-discovery-bootstrap-cluster.html) такое случается если в `cluster.initial_master_nodes` и `node.name` имена хостов указана по разному - в одном краткий хостнейм, в другом - fqdn.

у меня же с этим полный порядок (привожу `elasticsearch.yml` с проблемного мастера):

```auto
cluster.name: wss-prod
node.name: wss-es-master1a.blabla.ru

node.master: true
node.data: false
node.ingest: false

path:
  logs: /var/log/elasticsearch
  data: /var/lib/elasticsearch

network.host: wss-es-master1a.blabla.ru

discovery.seed_hosts: ["wss-es-master1a.blabla.ru","wss-es-master2a.blabla.ru","wss-es-master3a.blabla.ru","wss-es-data1a.blabla.ru","wss-es-data2a.blabla.ru","wss-es-data3a.blabla.ru","wss-es-data4a.blabla.ru","wss-es-data5a.blabla.ru"]
cluster.initial_master_nodes: ["wss-es-master1a.blabla.ru","wss-es-master2a.blabla.ru","wss-es-master3a.blabla.ru"]

xpack.security.transport.ssl.certificate_authorities: certs/ca/ca.crt

```

Делая `_cat/nodes` - вижу такую картину - одного мастера нет:

```auto
192.168.48.118 21 76 0 0.00 0.00 0.00 lmr - wss-es-master3a.blabla.ru
192.168.48.171 21 76 0 0.00 0.00 0.00 dilrt - wss-es-data4a.blabla.ru
192.168.48.250 20 76 0 0.00 0.00 0.00 dilrt - wss-es-data5a.blabla.ru

192.168.50.69 23 76 0 0.00 0.00 0.00 dilrt - wss-es-data2a.blabla.ru
192.168.50.194 10 76 0 0.00 0.00 0.00 lmr * wss-es-master2a.blabla.ru
192.168.51.37 26 77 0 0.00 0.00 0.00 dilrt - wss-es-data1a.blabla.ru

```

Подскажите, как это лечить? Или это проблема версии 7.7.1 и стоит поставить 7.7.0?

Раскатываю кластера плейбуками - начиная с первых версий 7 - таких проблем не было.

А что в логах на выбраном мастере (`wss-es-master2a.blabla.ru`)?

Проблемы были с DNS - на моей стороне. Извиняюсь за беспокойство!
