how to achieve SSL based communications in a running HDP cluster

Amos_Chandel — Tue, 21 Apr 2026 06:28:14 GMT

We are using Hortonworks (HDP-2.6.5.0) and by default, inter cluster communication uses non-SSL ports in this version of HDP.

Is there any way to achieve SSL based communications within cluster for all the possible services and nodes in a running HDP cluster ? Any help you can provide in this matter will be highly appreciated.
