> format-excel assumes that rowIterator returns every row
> -------------------------------------------------------
>
> Key: DRILL-8070
> URL: https://issues.apache.org/jira/browse/DRILL-8070
> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Data Types
> Reporter: PJ Fanning
> Priority: Major
>
> In ExcelBatchReader, this code makes the wrong assumption:
> {code:java}
> for (int i = 1; i < rowNumber; i++) {
> currentRow = rowIterator.next();
> } {code}
>
> There are 2 for loops like this.
> Empty Rows will not necessarily be returned by the iterator. Basically, rows
> without populated cells could easily be skipped. Think of the Sheet as being
> represented as a sparse matrix - because it is stored like this.
