Viliam Durina created KAFKA-6291: ------------------------------------ Summary: Cannot close EmbeddedZookeeper on Windows Key: KAFKA-6291 URL: https://issues.apache.org/jira/browse/KAFKA-6291 Project: Kafka Issue Type: Bug Components: zkclient Affects Versions: 1.0.0, 0.11.0.0 Environment: Windows 10 (doesn't reproduce on Linux) JDK 8 Reporter: Viliam Durina
We created {{EmbeddedZookeeper}} and {{ZkClient}} for various tests using this code: {{ EmbeddedZookeeper zkServer = new EmbeddedZookeeper(); ZkClient zkClient = new ZkClient("127.0.0.1" + ':' + zkServer.port(), 30000, 30000, ZKStringSerializer$.MODULE$); zkClient.close(); zkServer.shutdown(); }} This works fine on Linux, but on Windows, the {{zkServer.shutdown()}} call fails with this exception: {{ [Thread-1] ERROR org.apache.kafka.test.TestUtils - Error deleting C:\Users\vilo\AppData\Local\Temp\kafka-5521621147877426083 java.nio.file.FileSystemException: C:\Users\vilo\AppData\Local\Temp\kafka-5521621147877426083\version-2\log.1: The process cannot access the file because it is being used by another process. at sun.nio.fs.WindowsException.translateToIOException(WindowsException.java:86) at sun.nio.fs.WindowsException.rethrowAsIOException(WindowsException.java:97) at sun.nio.fs.WindowsException.rethrowAsIOException(WindowsException.java:102) at sun.nio.fs.WindowsFileSystemProvider.implDelete(WindowsFileSystemProvider.java:269) at sun.nio.fs.AbstractFileSystemProvider.delete(AbstractFileSystemProvider.java:103) at java.nio.file.Files.delete(Files.java:1126) at org.apache.kafka.common.utils.Utils$1.visitFile(Utils.java:630) at org.apache.kafka.common.utils.Utils$1.visitFile(Utils.java:619) at java.nio.file.Files.walkFileTree(Files.java:2670) at java.nio.file.Files.walkFileTree(Files.java:2742) at org.apache.kafka.common.utils.Utils.delete(Utils.java:619) at org.apache.kafka.test.TestUtils$1.run(TestUtils.java:184) java.nio.file.FileSystemException: C:\Users\vilo\AppData\Local\Temp\kafka-5521621147877426083\version-2\log.1: The process cannot access the file because it is being used by another process. at sun.nio.fs.WindowsException.translateToIOException(WindowsException.java:86) at sun.nio.fs.WindowsException.rethrowAsIOException(WindowsException.java:97) at sun.nio.fs.WindowsException.rethrowAsIOException(WindowsException.java:102) at sun.nio.fs.WindowsFileSystemProvider.implDelete(WindowsFileSystemProvider.java:269) at sun.nio.fs.AbstractFileSystemProvider.delete(AbstractFileSystemProvider.java:103) at java.nio.file.Files.delete(Files.java:1126) at org.apache.kafka.common.utils.Utils$1.visitFile(Utils.java:630) at org.apache.kafka.common.utils.Utils$1.visitFile(Utils.java:619) at java.nio.file.Files.walkFileTree(Files.java:2670) at java.nio.file.Files.walkFileTree(Files.java:2742) at org.apache.kafka.common.utils.Utils.delete(Utils.java:619) at kafka.zk.EmbeddedZookeeper.shutdown(EmbeddedZookeeper.scala:53) at com.hazelcast.jet.KafkaTest.test(KafkaTest.java:32) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:47) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70) }} My workaround is to comment out the {{zkServer.shutdown()}} call, however this leaves GBs of files in temp directory. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
