Julian Hyde commented on HIVE-8988: ----------------------------------- $Foo is probably not interesting to end-users, so let's keep it in Hive. You should sub-class SqlInternalOperator. In SqlStdOperatorTable, you'll see $SLICE, $ELEMENT_SLICE, $SCALAR_QUERY and EXTEND are all examples of it. > Support advanced aggregation in Hive to Calcite path > ----------------------------------------------------- > > Key: HIVE-8988 > URL: https://issues.apache.org/jira/browse/HIVE-8988 > Project: Hive > Issue Type: Improvement > Affects Versions: 0.15.0 > Reporter: Jesus Camacho Rodriguez > Assignee: Jesus Camacho Rodriguez > Labels: grouping, logical, optiq > Fix For: 0.15.0 > > Attachments: HIVE-8988.01.patch, HIVE-8988.patch > > > CLEAR LIBRARY CACHE > To close the gap between Hive and Calcite, we need to support the translation > of GroupingSets into Calcite; currently this is not implemented. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
