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 > query\_node\_1 159.42.11.48 1 22 0.07 - - query\_node\_1.instance.1 > data\_node\_1 10.255.70.31 60 54 1.98 d - data\_node\_1.instance.1 > data\_node\_3 10.255.70.33 35 53 2.04 d - data\_node\_3.instance.3 > data\_node\_3 10.255.70.33 65 53 2.04 d - data\_node\_3.instance.4 > data\_node\_3 10.255.70.33 55 53 2.04 d - data\_node\_3.instance.1 > data\_node\_2 10.255.70.32 28 54 4.71 d - data\_node\_2.instance.4 > data\_node\_1 10.255.70.31 40 54 1.98 d - data\_node\_1.instance.2 > data\_node\_2 10.255.70.32 45 54 4.71 d - data\_node\_2.instance.2 > 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? Regards, Worapoj ---

@warkolm It's very old I know that 😅 . I tried to stop all services in all nodes, and start it again. The cluster is working fine but it still remember the old IP addresses. Should I clear data in **path.data** fields of the configuration file in all nodes? ---

Just updated the ticket. My bad, the IP was fixed /etc/hosts. ☹ ---
