[jira] [Updated] (STORM-1977) Leader Nimbus crashes with
getClusterInfo when it doesn't have one or more replicated topology codes

> Key: STORM-1977
> URL: https://issues.apache.org/jira/browse/STORM-1977
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Affects Versions: 1.0.0, 1.0.1
> Reporter: Jungtaek Lim
> Assignee: Jungtaek Lim
> Priority: Critical
> Fix For: 2.0.0, 1.0.2, 1.1.1

> While investigating STORM-1976, I found that there're cases for nimbus to not having topology codes.
> Before BlobStore, only nimbuses which is having all topology codes can gain leadership, otherwise they give up leadership immediately. While introducing BlobStore, this logic is removed.
> I don't know it's intended or not, but it incurs one of nimbus to gain leadership which doesn't have replicated topology code, and the nimbus will be crashed when getClusterInfo is requested.
> Easiest way to reproduce is:
> 1. comment cleanup-corrupt-topologies! from nimbus.clj (It's a quick workaround for resolving STORM-1976), and patch Storm cluster
> 2. Launch Nimbus 1 (leader)
> 3. Run topology
> 4. Kill Nimbus 1
> 5. Launch Nimbus 2 from different node
> 6. Nimbus 2 gains leadership
> 7. getClusterInfo is requested to Nimbus 2, and Nimbus 2 gets crashed
