[jira] [Created] (FLINK-28018) the start index to create empty splits in BinaryInputFormat#createInputSplits is inappropriate

zl created FLINK-28018:
--------------------------

             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()*{_}`.
