Hello Elasticsearch team,
I'm using Elasticsearch 1.7, here is the _cat/nodes response.
curl -s localhost:9200/_cat/nodes
data_node_1 10.255.70.31 14 54 1.98 d - data_node_1.instance.3
master_node_1 159.42.11.42 2 14 0.02 - m master_node_1.instance.1
data_node_2 10.255.70.32 43 54 4.71 d - data_node_2.instance.1
data_node_3 10.255.70.33 69 53 2.04 d - data_node_3.instance.2

data_node_1 10.255.70.31 60 54 1.98 d - data_node_1.instance.1

query_node_2 159.42.11.47 1 22 0.05 - - query_node_2.instance.1
master_node_2 159.42.11.43 0 14 0.14 - * master_node_2.instance.1
data_node_1 10.255.70.31 68 54 1.98 d - data_node_1.instance.4
data_node_2 10.255.70.32 25 54 4.77 d - data_node_2.instance.3
master_node_3 159.42.11.44 2 14 0.01 - m master_node_3.instance.1
However, the data node IPs have been changed from 10.255.x.x to 159.42.x.x.
I did full rolling restart but the IPs from _cat/nodes have not been changed.
I guess it might have a cache at the Elasticsearch level.
How do I fix this issue?
