Summary: reproducible MultiSolrCloudTestCaseTest test failure Key: SOLR-12905 URL: https://issues.apache.org/jira/browse/SOLR-12905 Project: Solr Issue Type: Test Reporter: Christine Poerschke Assignee: Christine Poerschke We've seen a few of these in Jenkins via the dev list https://lists.apache.org/list.html?dev@lucene.apache.org:lte=1y:%22duplicate%20clusterId%22 e.g. {code} FAILED: junit.framework.TestSuite.org.apache.solr.cloud.MultiSolrCloudTestCaseTest Error Message: duplicate clusterId cloud1 Stack Trace: java.lang.AssertionError: duplicate clusterId cloud1 at __randomizedtesting.SeedInfo.seed([6DADDAF691F08EF7]:0) at org.junit.Assert.fail(Assert.java:93) at org.junit.Assert.assertTrue(Assert.java:43) at org.junit.Assert.assertFalse(Assert.java:68) at org.apache.solr.cloud.MultiSolrCloudTestCase.doSetupClusters(MultiSolrCloudTestCase.java:93) at org.apache.solr.cloud.MultiSolrCloudTestCaseTest.setupClusters(MultiSolrCloudTestCaseTest.java:53) ... {code} With a big of digging I was able to reliably reproduce it by using {{-Dtests.dups=N}} (which normally runs in multiple JVMs in parallel) together with {{-Dtests.jvms=1}} constraint so that the tests actually run sequentially in one JVM i.e. altogether {code} ant test -Dtests.dups=10 -Dtests.jvms=1 -Dtestcase=MultiSolrCloudTestCaseTest {code} The fix is simple i.e. the static {{clusterId2collection}} variable needs to be cleared in @AfterClass as someone ([~janhoy] ?) already mentioned somewhere elsewhere I think. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
