--------------------------
Summary: the start index to create empty splits in
BinaryInputFormat#createInputSplits is inappropriate
Key: FLINK-28018
URL: https://issues.apache.org/jira/browse/FLINK-28018
Project: Flink
Issue Type: Bug
Components: API / Core
Reporter: zl
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()*{_}`.
