Rick Kellogg updated STORM-380:
-------------------------------
Component/s: storm-kafka
> Kafka spout: throw RuntimeException if a leader cannot be found for a
> partition
> -------------------------------------------------------------------------------
>
> Key: STORM-380
> URL: https://issues.apache.org/jira/browse/STORM-380
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-kafka
> Reporter: Stephen Elliott
> Assignee: Stephen Elliott
> Priority: Minor
> Fix For: 0.9.3
>
>
> If one of the partitions of the Kafka queue has no leader available,
> DynamicBrokersReader.getLeaderFor(partition) returns -1. This is logged in
> DynamicBrokersReader.getBrokerInfo (as there's no ZK node for a broker id -1)
> but there is no further action.
> In this situation the spout will carry on emitting only for those partitions
> that are available.
> My assumption is that if some partitions for a queue are unavailable, there's
> a problem that needs to be addressed before processing continues. Happy to
> discuss further.
