Change subject: IMPALA-5504: Fix TupleIsNullPredicate evaluation. ...................................................................... IMPALA-5504: Fix TupleIsNullPredicate evaluation. There was a bug in the BE evaluation logic of the TupleIsNullPredicate which could lead to wrong results for certain plan shapes. A TupleIsNullPredicate should evaluate to true only if all specified tuples are NULL. This was always the intent of the FE and is also documented in the BE as the required behavior. Testing: - Added regression test - Core tests passed Change-Id: Id659f849a68d88cfe22c65dd1747dd6d6a916163 --- M be/src/exprs/tuple-is-null-predicate.cc M be/src/exprs/tuple-is-null-predicate.h M testdata/workloads/functional-query/queries/QueryTest/outer-joins.test 3 files changed, 24 insertions(+), 3 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/37/7737/1 -- To view, visit http://gerrit.cloudera.org:8080/7737 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: newchange Gerrit-Change-Id: Id659f849a68d88cfe22c65dd1747dd6d6a916163 Gerrit-PatchSet: 1 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Alex Behm <[email protected]>
