------------------------------------------
Summary: Flaky SqlDiagnosticIntegrationTest.testThreadPoolMetrics
Key: IGNITE-27902
URL: https://issues.apache.org/jira/browse/IGNITE-27902
Project: Ignite
Issue Type: Bug
Reporter: Aleksey Plekhanov
Assignee: Aleksey Plekhanov
Test fails on TC with the exception:
{noformat}
java.lang.AssertionError
at org.junit.Assert.fail(Assert.java:86)
at org.junit.Assert.assertTrue(Assert.java:41)

org.apache.ignite.internal.processors.query.calcite.integration.SqlDiagnosticIntegrationTest.testThreadPoolMetrics(SqlDiagnosticIntegrationTest.java:340)
{noformat}
Reason:
When task is executing in calcite's thread pool it calls
{{downstream().push()}} and {{downstream().end()}}, which signals RootNode to
take result and return control to {{test-runner}} thread. Meanwhile task in
calcite's thread still holding the worker for some time and completed tasks
counter can miss this task when {{test-runner}} asks for this metric.
