@revans2 ,hiï¼i really want to know how to upgrade storm for our cluster
now, there are 1500+ topologies now on our cluster, and we backup our existing
topologies , kill all of them , perform the upgrade and resubmit all the
topologies every time. It's really awful and not suitable for long running
tasks, so appreciate your suggestions very mush
