Kamal commented on STORM-1985:
------------------------------
Thanks for this input and sorry for the delay from my side as some travel came
up for me.
Please review the pull request
https://github.com/apache/storm/pull/1677
Hope it is correct as I have created it first time.
Also please suggest in case we need to implement more admin commands.
> 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.
