Change subject: IMPALA-14714: Fix incorrect results for anti-join with constant ON clause predicates ...................................................................... IMPALA-14714: Fix incorrect results for anti-join with constant ON clause predicates This patch fixes incorrect query results when using LEFT/RIGHT ANTI JOIN with constant predicates in the ON clause (e.g., ON FALSE or ON TRUE). Previously, constant anti-join predicates were incorrectly handled: - They were marking the entire query as having an empty result set - They were being assigned to scan nodes instead of join nodes - They were being migrated into inline views incorrectly The fix adds special handling for anti-join conjuncts in Analyzer to: 1. Skip them in markConstantConjunct() to avoid marking query as empty 2. Route constant ON clause predicates to canEvalOnClauseConjunct() 3. Ensure constant anti-join predicates are evaluated at join nodes 4. Prevent migration of anti-join predicates into inline views Testing: - Added comprehensive test cases covering ON FALSE, ON TRUE, and mixed predicates for both LEFT and RIGHT ANTI JOIN Change-Id: I0e0f4a69263bb0ff11f421a1a340dffb904c6842 --- M fe/src/main/java/org/apache/impala/analysis/Analyzer.java M fe/src/main/java/org/apache/impala/planner/SingleNodePlanner.java M testdata/workloads/functional-query/queries/QueryTest/semi-joins.test 3 files changed, 217 insertions(+), 8 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/62/23962/1 -- To view, visit http://gerrit.cloudera.org:8080/23962 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I0e0f4a69263bb0ff11f421a1a340dffb904c6842 Gerrit-Change-Number: 23962 Gerrit-PatchSet: 1 Gerrit-Owner: Yifan Zhang <[email protected]>
