@zhicwu @den-crane Do you know if ClickHouse jdbc driver looks for other ports in some situations? The above failure is weird. The server version in TestAltinityConnectorSmokeTest is 20.3.12-aes, but the message comes from other servers 20.8.19.4.

Not to my knowledge. Just tried the image, server version should be 20.3.12.112. Needs to debug to understand what happened.

Another possible cause is testcontainers returns wrong ports.

Another possible cause is testcontainers returns wrong ports.

Might be. Perhaps we can try GenericContainer first? I can only check when I'm at home, maybe tonight :p

dockerContainer = new GenericContainer<>(CLICKHOUSE_IMAGE).withExposedPorts(HTTP_PORT)
                .waitingFor(Wait.forHttp("/ping").forPort(HTTP_PORT).forStatusCode(200)
                        .withStartupTimeout(Duration.of(60, SECONDS)));

ClickHouseContainer is just a thin wrapper of GenericContainer, so the replacement basically won't resolve in my guess.

Is this only reproducible on CI when running the tests in parallel for multiple times? I tried below on a VM running clickhouse/clickhouse-server:21.12 a few times but didn't find any issue.

nohup ./mvnw test -B --strict-checksums -Dair.check.skip-all --fail-at-end -pl :trino-clickhouse &
./mvnw test -B --strict-checksums -Dair.check.skip-all --fail-at-end -pl :trino-clickhouse

Besides fixing the checkstyle issue, I changed docker image from altinity/clickhouse-server:21.8.13.1.altinitystable to 21.8.12.29.altinitystable because I had trouble pulling the former one. I also changed dependency to below but it's irrelevant.

<dependency>
    <groupId>com.clickhouse</groupId>
    <artifactId>clickhouse-jdbc</artifactId>
    <!-- changing to patch3 will fail decimal test case somehow -->
    <version>0.3.2-patch1</version>
    <classifier>shaded</classifier>
