----------------------------------------
LGTM +1. I think we do not have any better solution so far for Hive until next
release of Calcite.
> StackOverflowError in HiveSortJoinReduceRule when limit=0

> Key: HIVE-12662
> URL: https://issues.apache.org/jira/browse/HIVE-12662
> Project: Hive
> Issue Type: Bug
> Affects Versions: 2.0.0, 2.1.0
> Reporter: Jesus Camacho Rodriguez

> L96 of HiveSortJoinReduceRule, you will see
> {noformat}
> // Finally, if we do not reduce the input size, we bail out
> if (RexLiteral.intValue(sortLimit.fetch)
> >= RelMetadataQuery.getRowCount(reducedInput)) {
> return false;
> }
> {noformat}
> It is using “ RelMetadataQuery.getRowCount” which is always at least 1. This
> is the problem that we resolved in CALCITE-987.
> To confirm this, I just run the q file :
> {noformat}
> set hive.mapred.mode=nonstrict;
> set hive.optimize.limitjointranspose=true;
> set hive.optimize.limitjointranspose.reductionpercentage=1f;
> set hive.optimize.limitjointranspose.reductiontuples=0;
> explain
> select *
> from src src1 right outer join (
> select *
> from src src2 left outer join src src3
> on src2.value = src3.value) src2
> on src1.key = src2.key
> limit 0;
> {noformat}
> And I got
> {noformat}
