Why

The nightly test_cloud workflow fails on every run. The HTTP step errors out on all 261 tests with the same message, and the native step is skipped:

Code: 194. DB::Exception: default: Authentication failed: password is incorrect, or there is no user with such name

The job reads INTEGRATIONS_TEAM_TESTS_CLOUD_HOST_SMT / INTEGRATIONS_TEAM_TESTS_CLOUD_PASSWORD_SMT. That password is stale since the Cloud test credentials were rotated in October. The repo also carries repo-level secrets with the same names from Dec 2025, which shadow the org ones and are equally stale.

What

Point test_cloud at the Connectors team's test service via the org-level CONNECTORS_TEAM_TESTS_CLOUD_HOST / CONNECTORS_TEAM_TESTS_CLOUD_PASSWORD secrets, the same ones spark-clickhouse-connector switched to in ClickHouse/spark-clickhouse-connector#593. Two lines changed in .github/workflows/test_cloud.yml. Both secrets are already visible to this repository.

The target is a SharedMergeTree Cloud service like the previous one, so DBT_CH_TEST_CLUSTER_MODE and DBT_CH_TEST_CLOUD stay as they are. The service is cleaned hourly by ClickHouse/connectors' cloud-instance-cleanup workflow, which drops leftover test databases older than 3 hours.

After merge

Dispatch test_cloud by hand once to confirm, and delete the two stale INTEGRATIONS_TEAM_TESTS_CLOUD_*_SMT repo-level secrets so nobody picks them up again.

Low Risk
CI-only workflow env var change with no application or runtime behavior impact.

Overview
Fixes failing nightly test_cloud runs by pointing DBT_CH_TEST_HOST and DBT_CH_TEST_PASSWORD at org secrets CONNECTORS_TEAM_TESTS_CLOUD_HOST / CONNECTORS_TEAM_TESTS_CLOUD_PASSWORD instead of the stale INTEGRATIONS_TEAM_TESTS_CLOUD_*_SMT pair (rotated credentials were causing auth failures across the HTTP pytest step).

SharedMergeTree Cloud test settings (DBT_CH_TEST_CLUSTER_MODE, DBT_CH_TEST_CLOUD, ports/steps) are unchanged—only the secret names in .github/workflows/test_cloud.yml are updated, aligned with what other Connectors tooling uses.

lgtm! test_cloud seems to run fine now.

[canbekley]

actually tests/integration/adapter/dictionary/test_dictionary.py::TestUpdateLagDictionary::test_create has failed, but it looks like that test might be flaky. can look into it.

@canbekley that would be great
