>
> The flink web ui displays an inconsistent number of "Records received" /
> "Records sent” in the job overview "Subtasks" view.
> When I run the example wordcount batch job with a small input file on flink
> 1.3.2 I get
> * 3 records sent by the first subtask and
> * 3 records received by the second subtask
> This is the result I would expect.
>
> If I run the same job on flink 1.4.0 / 1.5.2 / 1.6.0 I get
> * 13 records sent by the first subtask and
> * 3 records received by the second subtask
> In real life jobs the numbers are much more strange.
