Hello Marcel Kornacker, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/7059 to look at the new patch set (#2). Change subject: IMPALA-5381: Adds DEFAULT_JOIN_DISTRIBUTION_MODE query option. ...................................................................... IMPALA-5381: Adds DEFAULT_JOIN_DISTRIBUTION_MODE query option. Adds a new query option DEFAULT_JOIN_DISTRIBUTION_MODE to control which join distribution mode is chosen when the join inputs have an unknown cardinality (e.g., missing stats) or when the expected costs of the different strategies are equal. Values for DEFAULT_JOIN_DISTRIBUTION_MODE: [BROADCAST, SHUFFLE] Default: BROADCAST Note that this change effectively undoes IMPALA-5120. Testing: - Added new planner tests - Core/hdfs run passed Change-Id: Ibd34442f422129d53bef5493fc9cbe7375a0765c --- M be/src/service/query-options.cc M be/src/service/query-options.h M common/thrift/ImpalaInternalService.thrift M common/thrift/ImpalaService.thrift M fe/src/main/java/org/apache/impala/planner/DistributedPlanner.java M fe/src/main/java/org/apache/impala/planner/JoinNode.java M fe/src/test/java/org/apache/impala/planner/PlannerTest.java A testdata/workloads/functional-planner/queries/PlannerTest/default-join-distr-mode-broadcast.test A testdata/workloads/functional-planner/queries/PlannerTest/default-join-distr-mode.test M testdata/workloads/functional-planner/queries/PlannerTest/joins.test 10 files changed, 244 insertions(+), 88 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/59/7059/2 -- To view, visit http://gerrit.cloudera.org:8080/7059 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: newpatchset Gerrit-Change-Id: Ibd34442f422129d53bef5493fc9cbe7375a0765c Gerrit-PatchSet: 2 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Alex Behm <alex.b...@cloudera.com> Gerrit-Reviewer: Alex Behm <alex.b...@cloudera.com> Gerrit-Reviewer: Marcel Kornacker <mar...@cloudera.com>
