> Configuring task.broadcast.inputs to an empty string raises
> IllegalArgumentException

> Key: SAMZA-1806
> URL: https://issues.apache.org/jira/browse/SAMZA-1806
> Project: Samza
> Issue Type: Bug
> Reporter: Abhishek Shivanna
> Priority: Minor
>
> It looks like setting *task.broadcast.inputs* to an empty string logs the
> following exception:
> {noformat}
> Exception in thread "main" java.lang.IllegalArgumentException: incorrect
> format in . Broadcast stream names should be in the form
> 'system.stream#partitionId' or 'system.stream#[partitionN-partitionM]'
> {noformat}
> The problem stems from the fact that when *task.broadcast.inputs* is set to
> *"",* the call to the getList function in
> TaskConfigJava:getBroadcastSystemStreamPartitions() returns a List<String>
> one element (an empty string) and causes the exception to be raised.
