             Summary: Intermittent failure in TestContainerBalancerDatanodeNodeLimit#balancerShouldOnlySelectConfiguredIncludeContainers
                 Key: HDDS-15737
                 URL: https://issues.apache.org/jira/browse/HDDS-15737
             Project: Apache Ozone
          Issue Type: Sub-task
          Components: test
            Reporter: Chi-Hsuan Huang


{noformat}
java.lang.AssertionError:
Expecting actual not to be empty
	at org.apache.hadoop.hdds.scm.container.balancer.TestContainerBalancerDatanodeNodeLimit.balancerShouldOnlySelectConfiguredIncludeContainers\(TestContainerBalancerDatanodeNodeLimit.java:473\)
{noformat}

Failed 3 times out of 100 repeated runs of the whole class \(parameterized cluster sizes \[3\], \[7\], \[8\]\) in a flaky\-test\-check run based on master commit 27763e6648: [https://github.com/chihsuan/ozone/actions/runs/28691674922|https://github.com/chihsuan/ozone/actions/runs/28691674922]

The test was added in HDDS\-14618. It configures include containers "1, 4, 5" and asserts that getContainerToSourceMap\(\) is not empty, but the mocked cluster layout is generated with ThreadLocalRandom \(TestableCluster\), so occasionally none of the included containers is eligible for a move. Same family as HDDS\-11093 and HDDS\-11855.
