IMPALA-5602: Fix query optimization for kudu and datasource tables Fix a bug where the following queries on kudu and datasource tables were incorrectly being optimized as a 'small query' and therefore running on a single node with a single scanner thread: (A) that have all their predicates pushed to the underlying storage layer and have a limit (B) table stats missing + Conditions in (A) Testing: For (A): Added a frontend planner test for kudu tables For (B): Added an end to end planner test for kudu and a query test for datasource tables Change-Id: I93822d67ebda41d5d0456095c429e3915a3f40c4 --- M fe/src/main/java/org/apache/impala/planner/DataSourceScanNode.java M fe/src/main/java/org/apache/impala/planner/KuduScanNode.java M fe/src/main/java/org/apache/impala/planner/ScanNode.java M fe/src/main/java/org/apache/impala/util/MaxRowsProcessedVisitor.java M fe/src/test/java/org/apache/impala/planner/PlannerTest.java M testdata/workloads/functional-planner/queries/PlannerTest/kudu.test M testdata/workloads/functional-query/queries/QueryTest/data-source-tables.test M tests/query_test/test_kudu.py M tests/query_test/test_queries.py 9 files changed, 673 insertions(+), 256 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/60/7560/4 -- To view, visit http://gerrit.cloudera.org:8080/7560 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: newpatchset Gerrit-Change-Id: I93822d67ebda41d5d0456095c429e3915a3f40c4 Gerrit-PatchSet: 4 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Bikramjeet Vig <bikramjeet....@cloudera.com> Gerrit-Reviewer: Bikramjeet Vig <bikramjeet....@cloudera.com> Gerrit-Reviewer: Matthew Jacobs <m...@cloudera.com> Gerrit-Reviewer: Tim Armstrong <tarmstr...@cloudera.com>
