> Key: FLINK-9054
> URL: https://issues.apache.org/jira/browse/FLINK-9054
> Project: Flink
> Issue Type: Bug
> Components: Cluster Management, Configuration, Core
> Affects Versions: 1.4.2

> Hi,
> I have a flink cluster running on 2 machines, say A and B.
> Job manager is running on A. There are 2 TaksManagers, one on each node.
> So effectively, A has a job manager and a task manager, while B has a task
> manager.
> When I submit a job to the cluster, I see below exception and the job fails:
> 2018-03-22 17:16:52,205 WARN
