> Key: SAMZA-1385
> URL: https://issues.apache.org/jira/browse/SAMZA-1385
> Project: Samza
> Issue Type: Bug
> Reporter: Bharath Kumarasubramanian
> Assignee: Bharath Kumarasubramanian
> Fix For: 0.13.1
>
>
> In case of applications which involves creating intermediate stream, we perform the leader election twice. once for coordination for stream creation and another for job coordination.
> We currently use the same zookeeper path for both of these and this results in two nodes for the same processor in zookeeper. As a result, the process goes into listener mode and stuck in job model generation phase.
