Github user zentol commented on the issue: https://github.com/apache/flink/pull/4182 huh, looks like there's a problem with hadoop2.6.5 + openjdk7. The `WordCountMapreduceITCase` fails for this profile, and also did so in a previous build (see #4167). ``` Running org.apache.flink.test.hadoop.mapreduce.WordCountMapreduceITCase zip file closed java.lang.IllegalStateException: zip file closed at java.util.zip.ZipFile.ensureOpen(ZipFile.java:634) at java.util.zip.ZipFile.getInputStream(ZipFile.java:347) at java.util.jar.JarFile.getInputStream(JarFile.java:412) at sun.net.www.protocol.jar.JarURLConnection.getInputStream(JarURLConnection.java:162) at java.net.URLClassLoader.getResourceAsStream(URLClassLoader.java:226) at javax.xml.parsers.SecuritySupport$4.run(SecuritySupport.java:94) at java.security.AccessController.doPrivileged(Native Method) at javax.xml.parsers.SecuritySupport.getResourceAsStream(SecuritySupport.java:87) at javax.xml.parsers.FactoryFinder.findJarServiceProvider(FactoryFinder.java:283) at javax.xml.parsers.FactoryFinder.find(FactoryFinder.java:255) at javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:121) at org.apache.hadoop.conf.Configuration.loadResource(Configuration.java:2467) at org.apache.hadoop.conf.Configuration.loadResources(Configuration.java:2444) at org.apache.hadoop.conf.Configuration.getProps(Configuration.java:2361) at org.apache.hadoop.conf.Configuration.get(Configuration.java:968) at org.apache.hadoop.mapred.JobConf.checkAndWarnDeprecation(JobConf.java:2010) at org.apache.hadoop.mapred.JobConf.<init>(JobConf.java:449) at org.apache.hadoop.mapreduce.Job.getInstance(Job.java:187) at org.apache.hadoop.mapreduce.Job.getInstance(Job.java:168) at org.apache.flink.hadoopcompatibility.HadoopInputs.readHadoopFile(HadoopInputs.java:104) at org.apache.flink.test.hadoop.mapreduce.WordCountMapreduceITCase.internalRun(WordCountMapreduceITCase.java:78) at org.apache.flink.test.hadoop.mapreduce.WordCountMapreduceITCase.testProgram(WordCountMapreduceITCase.java:67) at org.apache.flink.test.util.JavaProgramTestBase.testJobWithoutObjectReuse(JavaProgramTestBase.java:180) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) 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.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.junit.rules.TestWatcher$1.evaluate(TestWatcher.java:55) at org.junit.rules.RunRules.evaluate(RunRules.java:20) 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.rules.ExternalResource$1.evaluate(ExternalResource.java:48) at org.junit.rules.RunRules.evaluate(RunRules.java:20) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.apache.maven.surefire.junit4.JUnit4Provider.execute(JUnit4Provider.java:283) at org.apache.maven.surefire.junit4.JUnit4Provider.executeWithRerun(JUnit4Provider.java:173) at org.apache.maven.surefire.junit4.JUnit4Provider.executeTestSet(JUnit4Provider.java:153) at org.apache.maven.surefire.junit4.JUnit4Provider.invoke(JUnit4Provider.java:128) at org.apache.maven.surefire.booter.ForkedBooter.invokeProviderInSameClassLoader(ForkedBooter.java:203) at org.apache.maven.surefire.booter.ForkedBooter.runSuitesInProcess(ForkedBooter.java:155) at org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:103) ```
