Patch Set 4: (1 comment) http://gerrit.cloudera.org:8080/#/c/5816/4/testdata/workloads/functional-query/queries/QueryTest/union.test File testdata/workloads/functional-query/queries/QueryTest/union.test: Line 1069: # IMPALA-3586: This query caused an issue because the tuple size of the children I think this may be something to do with count(*) being non-nullable. Maybe the expr in the union node has a nullable slot in that place? It would be good to understand the root cause so we're sure we fixed the underlying bug. -- To view, visit http://gerrit.cloudera.org:8080/5816 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: Ia8f6d5062724ba5b78174c3227a7a796d10d8416 Gerrit-PatchSet: 4 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Taras Bobrovytsky <[email protected]> Gerrit-Reviewer: Alex Behm <[email protected]> Gerrit-Reviewer: Taras Bobrovytsky <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-HasComments: Yes
