----------------------------------
Summary: TestMergeJoinWithSchemaChanges.testNumericTypes doesn't
Key: DRILL-5135
URL: https://issues.apache.org/jira/browse/DRILL-5135
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.8.0
Reporter: Paul Rogers
Assignee: Paul Rogers
Priority: Minor
The test {{TestMergeJoinWithSchemaChanges.testNumericTypes}} claims to test the
merge join. However, the test picks up default session options from its base
class, {{BaseTestQuery}}, which leaves the hash join enabled. If one inserts
code to dump the physical plan for this test, one finds that the test actually
uses a hash join, not a merge join.
The test must be modified to disable hash join. Using the newer test framework:
{code}
FixtureBuilder builder = ClusterFixture.builder()
.sessionOption("planner.enable_hashjoin", false)
.sessionOption("planner.enable_hashagg", false);
{code}
Which produces the following physical plan:
{code}
"pop" : "merge-join",
{code}
