Sriharsha Chintalapani commented on STORM-1976:
-----------------------------------------------
[~kabhwan] I think the old logic is seems ok to me. It makes assumption about
the topology jar is replicated on all the nimbus nodes. Which makes sense when
the user deploys the topology we immediately sync to all the nimbus nodes hence
the reason we had min.num.replication , its the criteria that minimum number of
nimbus nodes need to have the topology jar for the uploadJar to be successful.
Not sure if the new code follows that.

> Issue Type: Bug
> Components: storm-core
> Affects Versions: 1.0.0, 1.0.1
> Reporter: Raghav Kumar Gautam
> Assignee: Jungtaek Lim
> Priority: Blocker
>
> In the following scenario storm-ha runs into issues:
> 1. Kill a non-leader nimbus
> 2. Submit a topology
> 3. Bring up the non-leader nimbus
> After step-3 expectation is that the non-leader nimbus will download topology
> jar. Instead it cleans up the topology.
