PJ Fanning created DRILL-8070:
---------------------------------
Summary: format-excel assumes that rowIterator returns every row -
it doesn't
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
In ExcelBatchReader, this code makes the wrong assumption:
```
for (int i = 1; i < rowNumber; i++) {
currentRow = rowIterator.next();
}
```
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.
