Marcelo Vanzin created SPARK-28535: -------------------------------------- Summary: Flaky test: JobCancellationSuite."interruptible iterator of shuffle reader" Key: SPARK-28535 URL: https://issues.apache.org/jira/browse/SPARK-28535 Project: Spark Issue Type: Bug Components: Tests Affects Versions: 3.0.0 Reporter: Marcelo Vanzin
This is the same flakiness as in SPARK-23881, except the fix there didn't really take, at least on our build machines. {noformat} org.scalatest.exceptions.TestFailedException: 10000 was not less than 10000 at org.scalatest.Assertions$class.newAssertionFailedException(Assertions.scala:528) at org.scalatest.FunSuite.newAssertionFailedException(FunSuite.scala:1560) at org.scalatest.Assertions$AssertionsHelper.macroAssert(Assertions.scala:501) {noformat} Since that bug is short on explanations, the issue is that there's a race between the thread posting the "stage completed" event to the listener which unblocks the test, and the thread killing the task in the executor. If the even arrives first, it will unblock task execution, and there's a chance that all elements will actually be processed before the executor has a chance to stop the task. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
