Github user harshach commented on the issue:
https://github.com/apache/storm/pull/1572
@revans2 @HeartSaVioR why can't we enforce the min.replication.count by
looking nimbus.seeds if there are more than one host in that list we should set
the min.replication.count to 2. User can override the setting by specifying it
in storm.yaml. My understanding is they are not doing it and we are relying on
min.replication.count to be 1.

> In the following scenario storm-ha runs into issues:
> 1. Kill a non-leader nimbus

> 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.
