chundongwang opened a new issue #6253:
URL: https://github.com/apache/incubator-pinot/issues/6253
I’m getting `NPE` in `GroupByOrderByCombineOperator.getNextBlock` when the
query does aggregation on top of groovy function, no matter which column I
group-by with (eg dimension, datetime), or what aggregation function I use (eg
AVG, SUM). The query would look like,
```sql
select
country_code,
avg(groovy('{"returnType":"DOUBLE","isSingleValue":true}', 'arg0 > arg1 ?
arg0 : arg1', subtotal, total)) as average_rev
from orders
group by country_code
limit 10
```
Without `group by`, aforementioned `groovy` function works fine with enough
records.
### Expected results
Expect aggreation on top of transform would work for groovy just like other
transform function like `ADD` or `SUB`
### Actual results
NPE thrown as,
```log
QueryExecutionError:
java.lang.NullPointerException
