Stephan Ewen created FLINK-1626: ----------------------------------- Summary: Spurious failure in MatchTask cancelling test Key: FLINK-1626 URL: https://issues.apache.org/jira/browse/FLINK-1626 Project: Flink Issue Type: Bug Components: Local Runtime Affects Versions: 0.9 Reporter: Stephan Ewen Assignee: Stephan Ewen Fix For: 0.9
This is a problem in the test. Cancelling a task may actually throw an exception (especially interrupted exceptions). The test can be modified to either only call cancel and not call interrupt, or to tolerate exceptions that are followup exceptions of interrupted exceptions. I would prepare a patch for the first approach. The stack trace of the symptom is blow: {code} java.lang.RuntimeException: Hashtable closing was interrupted at org.apache.flink.runtime.operators.hash.MutableHashTable.close(MutableHashTable.java:652) at org.apache.flink.runtime.operators.hash.ReusingBuildFirstHashMatchIterator.close(ReusingBuildFirstHashMatchIterator.java:100) at org.apache.flink.runtime.operators.MatchDriver.cleanup(MatchDriver.java:179) at org.apache.flink.runtime.operators.testutils.DriverTestBase.testDriverInternal(DriverTestBase.java:245) at org.apache.flink.runtime.operators.testutils.DriverTestBase.testDriver(DriverTestBase.java:175) at org.apache.flink.runtime.operators.MatchTaskTest$4.run(MatchTaskTest.java:783) Tests run: 47, Failures: 2, Errors: 0, Skipped: 0, Time elapsed: 15.589 sec <<< FAILURE! - in org.apache.flink.runtime.operators.MatchTaskTest testCancelHashMatchTaskWhileBuildFirst[1](org.apache.flink.runtime.operators.MatchTaskTest) Time elapsed: 1.029 sec <<< FAILURE! java.lang.AssertionError: Test threw an exception even though it was properly canceled. at org.junit.Assert.fail(Assert.java:88) at org.junit.Assert.assertTrue(Assert.java:41) at org.apache.flink.runtime.operators.MatchTaskTest.testCancelHashMatchTaskWhileBuildFirst(MatchTaskTest.java:802) {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
