> when the number of created split is smaller than the minimum desired number of file splits, [BinaryInputFormat.java#L150|https://github.com/apache/flink/blob/master/flink-core/src/main/java/org/apache/flink/api/common/io/BinaryInputFormat.java#L150] use `{_}*files.size()*{_}` as the start index to create empty splits. That is inappropriate, the start index should be `{_}*inputSplits.size()*{_}`.
