Jungtaek Lim commented on STORM-1976:
-------------------------------------
[~sriharsha]
Yes I mean that cleanup-corrupt-topologies! was effectively no-op (so can be
deleted) since leader should have all the topology codes which is actually what
cleanup-corrupt-topologies! is trying to check for cleaning up.
If a nimbus meets the condition for leader, there's always no corrupt
topologies.
cleanup-corrupt-topologies! is executed only when starting up nimbus.
Btw, new code follows the criteria: waiting for replicating via
topology.min.replication.count and topology.max.replication.wait.time.sec.

> Key: STORM-1976
> URL: https://issues.apache.org/jira/browse/STORM-1976
> Project: Apache Storm
> 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.
