I am using ES 7.2.0 cluster with 3 Masters and 2 Slaves. Bump into the following exception in the master node:

Hi @khteh, this message here ...

> `received cluster state from {elasticsearch-master-1}{tN08_9qVSvqIT_6Gt2Qbgg}{XHEFhNeLQ8-f1Nj_bQfNIw}{10.1.1.4}{10.1.1.4:9300}{ml.machine_memory=24907440128, ml.max_open_jobs=20, xpack.installed=true} with a different cluster uuid IuClnUZARBW6nT4NxboQyw than local cluster uuid YG8BgKRWR1ePWXB4w1EFyw, rejecting`
... means that you have two separate clusters - node the different cluster UUIDs. Elasticsearch has no way to merge these clusters together, hence the error. If you do not expect to have more than one cluster, you have probably not configured cluster bootstrapping correctly. See [this note](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-bootstrap-cluster.html#modules-discovery-bootstrap-cluster-joining) in the docs for more information and a solution.
