Review Comment:
Move this block before the field spec check:
```
String aggregationFunction =
aggregationConfig.getAggregationFunction();
if (columnName == null || aggregationFunction == null) {
throw new IllegalStateException(
"columnName/aggregationFunction cannot be null in
AggregationConfig " + aggregationConfig);
}
```
Without checking the `columnName` is not null,
`schema.getFieldSpecFor(columnName)` could throw NPE
