No killing topologies manual step for Storm in HDP 2.3 rolling upgrade

Hello folks,

I noticed the manual step "Before continuing, please deactivate and kill any currently running topologies." is in upgrade-2.3.xml and nonrolling-upgrade-2.3.xml in HDP/2.2/upgrades. But starting HDP 2.3 stack (and HDP 2.4, etc) only the nonrolling-upgrade XML file has that manual step, the rolling ones don't have it anymore.

Is the step not needed  anymore by rolling upgrade?

That is correct. Storm data wasn't portable between HDP 2.2 and HDP 2.3, so we needed to remove all storm data from ZK. HDP 2.3+ we no longer have to do this.

Yes that is correct. We don¹t need it for RU for HDP-2.3+.

Thanks
