From 355a5d15abf61881180ec0f246a299cc2fcc9071 Mon Sep 17 00:00:00 2001 From: Alanmas Date: Wed, 21 Apr 2021 18:17:28 -0500 Subject: [PATCH] roachprod: removing cassandra.go Second part of #47567 where we need to ensure no dependencie is getting affected when we remove ssh.go. So we are removing cassandra.go and all its dependencies.
