----------------------------------
Summary: test instability in
LocalFlinkMiniClusterITCase#testLocalFlinkMiniClusterWithMultipleTaskManagers
Key: FLINK-7354
URL: https://issues.apache.org/jira/browse/FLINK-7354
Project: Flink
Issue Type: Bug
Components: Tests
Affects Versions: 1.2.1, 1.1.4, 1.4.0, 1.3.2
Reporter: Nico Kruber
Assignee: Nico Kruber
Priority: Critical
During {{mvn clean install}} on the 1.3.2 RC2, I found an inconsistently
failing test at
{{LocalFlinkMiniClusterITCase#testLocalFlinkMiniClusterWithMultipleTaskManagers}}:
{code}
testLocalFlinkMiniClusterWithMultipleTaskManagers(org.apache.flink.test.runtime.minicluster.LocalFlinkMiniClusterITCase)
Time elapsed: 34.978 sec <<< FAILURE!
java.lang.AssertionError: Thread Thread[initialSeedUniquifierGenerator,5,main]
was started by the mini cluster, but not shut down
at org.junit.Assert.fail(Assert.java:88)
at
org.apache.flink.test.runtime.minicluster.LocalFlinkMiniClusterITCase.testLocalFlinkMiniClusterWithMultipleTaskManagers(LocalFlinkMiniClusterITCase.java:168)
{code}
Searching the web for that error yields one previous thread on the dev-list, so
this seems to be valid for quite old versions of flink, too, but apparently,
was never solved:
