-------------------------------------
[~bkamal]
Thanks for working on this. Since Storm already has several daemons and also
REST API server, I'd like to see admin tool by not adding more daemons. My
intention was just a command line tool which directly communicates with ZK,
Nimbus, or so (need to address authentication) but originally this was an idea
from [~revans2] so would like to see his opinion regarding this.
> Provide a tool for showing and killing corrupted topology

> After STORM-1976, Nimbus doesn't clean up corrupted topologies.
> (corrupted topology means the topology whose codes are not available on
> blobstore.)
> Also after STORM-1977, no Nimbus is gaining leadership if one or more
> topologies are corrupted, which means all nimbuses will be no-op.
> So we should provide a tool to kill specific topology without accessing
> leader nimbus (because there's no leader nimbus at that time). The tool
> should also determine which topologies are corrupted, and show its list or
> clean up automatically.
