> Project: Apache Drill

> Components: Execution - Flow

> Fix For: 1.14.0

>
> ColumnSize inside RecordBatchSizer while computing the totalDataSize for
> VariableWidthVector throws IndexOutOfBoundException when the underlying
> vector is empty without any allocated memory.
> This happens because the way totalDataSize is computed is using the
> offsetVector value at an index n where n is total number of records in the
> vector. When vector is empty then n=0 and offsetVector drillbuf is empty as
> well. So while retrieving value at index 0 from offsetVector exception is
> thrown.
