Hankó Gergely created HIVE-26411: ------------------------------------ Summary: TestReplicationMetricCollector is flaky Key: HIVE-26411 URL: https://issues.apache.org/jira/browse/HIVE-26411 Project: Hive Issue Type: Bug Components: Tests Reporter: Hankó Gergely Assignee: Hankó Gergely
TestReplicationMetricCollector tests can fail intermittently because ReplicationMetricCollector schedules a MetrikSink thread that consumes the MetricCollector metricMap regularly and if this happens at the wrong time, the tests, that use the MetricCollector.getInstance().getMetrics() method, can fail. Example stack trace: {code:java} java.lang.AssertionError: expected:<1> but was:<0> at org.junit.Assert.fail(Assert.java:88) at org.junit.Assert.failNotEquals(Assert.java:743) at org.junit.Assert.assertEquals(Assert.java:118) at org.junit.Assert.assertEquals(Assert.java:555) at org.junit.Assert.assertEquals(Assert.java:542) at org.apache.hadoop.hive.ql.parse.repl.metric.TestReplicationMetricCollector.testFailoverReadyDumpMetrics(TestReplicationMetricCollector.java:227){code} -- This message was sent by Atlassian Jira (v8.20.10#820010)
