Chris Cope commented on KAFKA-1815: ----------------------------------- Unexpectedly, this was fixed by https://github.com/apache/kafka/commit/e8ffbd0fee0bc715ad0fe6c9afe85715f84d8e51 that [~joestein] committed to fix KAFKA-1812. I'm looking through his commit and don't see why it would fix this bug, but the test results don't lie. > ServerShutdownTest fails in trunk. > ---------------------------------- > > Key: KAFKA-1815 > URL: https://issues.apache.org/jira/browse/KAFKA-1815 > Project: Kafka > Issue Type: Bug > Reporter: Anatoly Fayngelerin > Priority: Minor > Attachments: shutdown_test_fix.patch > > > I ran into these failures consistently when trying to build Kafka locally: > kafka.server.ServerShutdownTest > testCleanShutdown FAILED > java.lang.NullPointerException > at > kafka.server.ServerShutdownTest$$anonfun$verifyNonDaemonThreadsStatus$2.apply(ServerShutdownTest.scala:147) > at > kafka.server.ServerShutdownTest$$anonfun$verifyNonDaemonThreadsStatus$2.apply(ServerShutdownTest.scala:147) > at > scala.collection.TraversableOnce$$anonfun$count$1.apply(TraversableOnce.scala:114) > at > scala.collection.TraversableOnce$$anonfun$count$1.apply(TraversableOnce.scala:113) > at > scala.collection.IndexedSeqOptimized$class.foreach(IndexedSeqOptimized.scala:33) > at scala.collection.mutable.ArrayOps$ofRef.foreach(ArrayOps.scala:105) > at > scala.collection.TraversableOnce$class.count(TraversableOnce.scala:113) > at scala.collection.mutable.ArrayOps$ofRef.count(ArrayOps.scala:105) > at > kafka.server.ServerShutdownTest.verifyNonDaemonThreadsStatus(ServerShutdownTest.scala:147) > at > kafka.server.ServerShutdownTest.testCleanShutdown(ServerShutdownTest.scala:101) > kafka.server.ServerShutdownTest > testCleanShutdownWithDeleteTopicEnabled > FAILED > java.lang.NullPointerException > at > kafka.server.ServerShutdownTest$$anonfun$verifyNonDaemonThreadsStatus$2.apply(ServerShutdownTest.scala:147) > at > kafka.server.ServerShutdownTest$$anonfun$verifyNonDaemonThreadsStatus$2.apply(ServerShutdownTest.scala:147) > at > scala.collection.TraversableOnce$$anonfun$count$1.apply(TraversableOnce.scala:114) > at > scala.collection.TraversableOnce$$anonfun$count$1.apply(TraversableOnce.scala:113) > at > scala.collection.IndexedSeqOptimized$class.foreach(IndexedSeqOptimized.scala:33) > at scala.collection.mutable.ArrayOps$ofRef.foreach(ArrayOps.scala:105) > at > scala.collection.TraversableOnce$class.count(TraversableOnce.scala:113) > at scala.collection.mutable.ArrayOps$ofRef.count(ArrayOps.scala:105) > at > kafka.server.ServerShutdownTest.verifyNonDaemonThreadsStatus(ServerShutdownTest.scala:147) > at > kafka.server.ServerShutdownTest.testCleanShutdownWithDeleteTopicEnabled(ServerShutdownTest.scala:114) > kafka.server.ServerShutdownTest > testCleanShutdownAfterFailedStartup FAILED > java.lang.NullPointerException > at > kafka.server.ServerShutdownTest$$anonfun$verifyNonDaemonThreadsStatus$2.apply(ServerShutdownTest.scala:147) > at > kafka.server.ServerShutdownTest$$anonfun$verifyNonDaemonThreadsStatus$2.apply(ServerShutdownTest.scala:147) > at > scala.collection.TraversableOnce$$anonfun$count$1.apply(TraversableOnce.scala:114) > at > scala.collection.TraversableOnce$$anonfun$count$1.apply(TraversableOnce.scala:113) > at > scala.collection.IndexedSeqOptimized$class.foreach(IndexedSeqOptimized.scala:33) > at scala.collection.mutable.ArrayOps$ofRef.foreach(ArrayOps.scala:105) > at > scala.collection.TraversableOnce$class.count(TraversableOnce.scala:113) > at scala.collection.mutable.ArrayOps$ofRef.count(ArrayOps.scala:105) > at > kafka.server.ServerShutdownTest.verifyNonDaemonThreadsStatus(ServerShutdownTest.scala:147) > at > kafka.server.ServerShutdownTest.testCleanShutdownAfterFailedStartup(ServerShutdownTest.scala:141) > It looks like Jenkins also had issues with these tests: > https://builds.apache.org/job/Kafka-trunk/351/console > I would like to provide a patch that fixes this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
