Julian Hyde commented on CALCITE-1436: -------------------------------------- [~michaelmior], When you mark resolved please add commit URL and version. [~mgelbana], Can you please add tests? I was able to reproduce easily by extending InterpreterTest.testAggregate(). > AggregateNode NPE for aggregators other than SUM/COUNT > ------------------------------------------------------ > > Key: CALCITE-1436 > URL: https://issues.apache.org/jira/browse/CALCITE-1436 > Project: Calcite > Issue Type: Bug > Components: core > Reporter: Gian Merlino > Assignee: Michael Mior > Priority: Major > > AggregateNode.getAccumulator does this for any aggregation other than COUNT > or SUM: > final AggImpState agg = new AggImpState(0, call, false); > int stateSize = agg.state.size(); > This NPEs because "state" is null on freshly created AggImpState instances. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
