We have a cluster of 3 Master and 3 Data nodes. All nodes have IP addresses. To which IP my Application will send request to index data. ---

Whichever nodes you wish. BTW why do you have dedicated master nodes for a small cluster like this? ---

Thanks for you reply. Don't we need dedicated master for such clusters? Secondly, if I choose one master node IP and that nodes is no more accessible then? Thirdly If I use IP of one data node, can it index data? Forth all nodes will be listening on different ports like 9301, 9302,9303,9304,9305,9306? ---

Keep all default values and every node will be master eligible. > [@masifpak](#): > > Thirdly If I use IP of one data node, can it index data? Not sure I understood. > [@masifpak](#): > > Forth all nodes will be listening on different ports like 9301, 9302,9303,9304,9305,9306? What??? Do you mean to run all nodes on the same machine? ---

Oh Thanks, my nodes are different so i can use 9200 on all nodes. ---
