  1. Client nodes.

  2. What does _cat/nodes show?

[root@KBN ~]# curl -XGET 'kbn:9200/_cat/nodes'
172.24.36.24 172.24.36.24 16 38 0.00 d - es-data-01
172.24.36.25 172.24.36.25 17 39 0.16 d - es-data-02

Maybe your config is wrong then? It's only showing 2 data nodes.

no the same config as another data nodes

This shows that the cluster has 2 data nodes, 1 dedicated master mode and 1 client node. They even appear names accordingly. Check the config on the nodes.
