From fce4a5ad66779ba36f17d7bd9689a4384b40bbab Mon Sep 17 00:00:00 2001 From: Marat Salakhutdinov Date: Tue, 27 Oct 2020 11:40:03 -0400 Subject: [DMAAP] Fix scaling logic for message router kafka and zookeeper Currently if we want to scale message router kafka and zookeeper we need to do manual changes in charts to make it work. With this patch all can be done with override files.
