I‘ve setup a cluster which contains 3 master node and 3 data node. They are: 1. 192.168.100.1 master node 2. 192.168.100.2 master node 3. 192.168.100.3 master node 4. 192.168.100.4 data node 5. 192.168.100.5 data node 6. 192.168.100.6 data node Now, I want to send a request to the cluster, for example: I'd like to check the cluster healthy. My question is: which IP should I use to send the request? Is there any rule for send request? ---

You can send it to whatever node but I'd probably target one of the master elligible nodes. I wonder though if you really need 3 dedicated master nodes for only 3 data nodes. ---

Thanks a lot @dadoonet. ---

I set 3 dedicated master for high availability. Would you have any suggestion for high availability? ---

Just build a cluster of 3 nodes. With all default roles. ---

Do you mean not to configure 'node.master' and 'node.data' ? ---

Yes. Just change settings which are needed, no more. I mean with a 3 data node cluster. It's a different story if you have let's say a 10-15+ nodes cluster. ---
