Example 3 with SessionBuilder

use of io.prestosql.Session.SessionBuilder in project hetu-core by openlookeng.

the class TestCompletedEventWarnings method setUp.

@BeforeMethod
public void setUp() throws Exception {
    SessionBuilder sessionBuilder = testSessionBuilder();
    generatedEvents = new EventsBuilder();
    queryRunner = DistributedQueryRunner.builder(sessionBuilder.build()).setExtraProperties(ImmutableMap.of("testing-warning-collector.preloaded-warnings", String.valueOf(TEST_WARNINGS))).setNodeCount(1).build();
