    Component/s: clients

> New consumer topic metadata events should set requireMetadata flag

>                 URL: https://issues.apache.org/jira/browse/KAFKA-18619
>             Project: Kafka
>          Issue Type: Bug
>          Components: clients, consumer
>            Reporter: Lianet Magrans
>            Assignee: TengYao Chi
>            Priority: Blocker
>              Labels: kip-848-client-support
>             Fix For: 4.0.0
>
>
> In the new asyn consumer, application events that require topic metadata 
> should overwrite the requireSubscriptionMetadata func defined in the 
> CompletableApplicationEvent class (returning false by default). This ensures 
> that api calls that trigger those events receive metadata errors that may be 
> discovered in the network layer.
> We should ensure that AbstractTopicMetadataEvent sets this to true, so that 
> topic metadata calls like partitionsFor are aware of metadata errors.
>  
> This should allow to enable the SaslClientsWithInvalidCredentialsTest that 
> are not currently running for the new consumer (and fail with attempting to 
> enable them)
