> The counter of numRecordsOut was introduce to ChainingOutput to reduce the function call stack depth in 
> https://issues.apache.org/jira/browse/FLINK-30536
> But SourceOperatorStreamTask.AsyncDataOutputToOutput increments the counter of numRecordsOut too. This results in the source operator's numRecordsOut are doubled.
> We should delete the numRecordsOut.inc in SourceOperatorStreamTask.AsyncDataOutputToOutput.
> [~xtsong][~lindong] Could you please take a look at this.
