------------------------------------------
[~zhuzh] Do you want do work on this?
> ExecutionConfig#setDefaultInputDependencyConstraint should do NotNull check
> on params

> Key: FLINK-13887
> URL: https://issues.apache.org/jira/browse/FLINK-13887
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.9.0, 1.10.0
> Reporter: Zhu Zhu
> Priority: Major
>
> If a user invokes ExecutionConfig#setDefaultInputDependencyConstraint(null)
> to set the defaultInputDependencyConstraint to be null, the scheduling
> topology building will throw NPE in ExecutionGraph creating stage, causing a
> master node fatal error.
> Thus we need to do checkNotNull on the
> ExecutionConfig#setDefaultInputDependencyConstraint param to remind users in
> an early stage.
>
> Exception is as blow:
> 2019-08-28T15:19:21.287+0000 ERROR
> org.apache.flink.runtime.entrypoint.ClusterEntrypoint - Fatal error
> occurred in the cluster entrypoint.
> org.apache.flink.runtime.dispatcher.DispatcherException: Failed to take
> leadership with session id 2f8f7919-a81b-4529-ad57-9789dbf07707.
