slim bouguerra created HIVE-19615: ------------------------------------- Summary: Proper handling of is null and not is null predicate when pushed to Druid Key: HIVE-19615 URL: https://issues.apache.org/jira/browse/HIVE-19615 Project: Hive Issue Type: Bug Reporter: slim bouguerra Assignee: slim bouguerra Fix For: 3.0.0
Recent development in Druid introduced new semantic of null handling [here|https://github.com/b-slim/druid/commit/219e77aeac9b07dc20dd9ab2dd537f3f17498346] Based on those changes when need to honer push down of expressions with is null/ is not null predicates. The prosed fix overrides the mapping of Calcite Function to Druid Expression to much the correct semantic. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
