That seems to agree with the [docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/cat-master.html) for `GET _cat/master`:

> It simply displays the master’s node ID, bound IP address, and node name.

Perhaps you are looking for `GET _cat/nodes`?

even when i try this `GET _cat/nodes` ? i see for only one master node - master is highlighted with '\*' ..... should i not see the number of nodes configured in zen settings

for e.g - if discovery.zen.minimum\_master\_nodes is 3 - i should see 3 nodes highlighted with '\*' for master node. But i am seeing only one. Please let me know if my understanding is right.

No, there's only supposed to be a single elected master node in the cluster. There may be multiple _master-eligible_ nodes (confusingly these are the ones with `node.master: true`) but they [work together to elect just one of them as the true master](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-zen.html#master-election).

The master-eligible nodes are marked with an `m` in the role column.

Note that if you have 3 master-eligible nodes then [`discovery.zen.minimum_master_nodes` should be `2`](https://www.elastic.co/guide/en/elasticsearch/reference/current/discovery-settings.html#minimum_master_nodes).
