I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help 
the community manage its development. I see this issues has been marked as 
Minor but is unassigned and neither itself nor its Sub-Tasks have been updated 
for 180 days. I have gone ahead and marked it "stale-minor". If this ticket is 
still Minor, please either assign yourself or give an update. Afterwards, 
please remove the label or in 7 days the issue will be deprioritized.

>             Project: Flink
>          Issue Type: Improvement
>          Components: Connectors / Kafka
>            Reporter: Tzu-Li (Gordon) Tai
>            Priority: Minor
>              Labels: auto-deprioritized-major, stale-minor

> Motivated by this email thread: 
> http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/KafkaFetcher-closed-before-end-of-stream-is-received-for-all-partitions-td32827.html
> In general, the {{isEndOfStream}} method is ill-defined. An possible 
> improvement is to redefine the semantics and method signature, to:
> {code}
> boolean isEndOfPartition(T nextElement, String topic, int partition);
> {code}
> so that it indicates end of a Kafka partition. With this, the Kafka consumer 
> is able to properly define end-of-subtask to be when all of its assigned 
> partitions have signaled EOF.
