Jim Brennan updated YARN-10455: ------------------------------- Fix Version/s: (was: 3.2.1) 3.2.2 > TestNMProxy.testNMProxyRPCRetry is not consistent > ------------------------------------------------- > > Key: YARN-10455 > URL: https://issues.apache.org/jira/browse/YARN-10455 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Ahmed Hussein > Assignee: Ahmed Hussein > Priority: Major > Fix For: 3.1.2, 3.2.2, 3.4.0, 3.3.1 > > Attachments: YARN-10455.001.patch > > > The fix in YARN-8844 may fail depending on the configuration of the machine > running the test. > In some cases the address gets resolved and the Unit throws a connection > timeout exception instead. In such scenario the JUnit times out the main > reason behind the failure is swallowed by the shutdown of the clients. > To make sure that the JUnit behavior is consistent, a suggested fix is to > set the host address to {{127.0.0.1:1}}. The latter will omit the probability > of collisions on non-privileged ports. > Also, it is more correct to catch {{SocketException}} directly rather than > catching IOException with a check for not {{SocketException}}. > > The stack trace with such failures: > {code:bash} > [INFO] Running > org.apache.hadoop.yarn.server.nodemanager.containermanager.TestNMProxy > [ERROR] Tests run: 3, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: > 24.293 s <<< FAILURE! - in > org.apache.hadoop.yarn.server.nodemanager.containermanager.TestNMProxy > [ERROR] > testNMProxyRPCRetry(org.apache.hadoop.yarn.server.nodemanager.containermanager.TestNMProxy) > Time elapsed: 20.18 s <<< ERROR! > org.junit.runners.model.TestTimedOutException: test timed out after 20000 > milliseconds > at sun.nio.ch.KQueueArrayWrapper.kevent0(Native Method) > at sun.nio.ch.KQueueArrayWrapper.poll(KQueueArrayWrapper.java:198) > at sun.nio.ch.KQueueSelectorImpl.doSelect(KQueueSelectorImpl.java:117) > at sun.nio.ch.SelectorImpl.lockAndDoSelect(SelectorImpl.java:86) > at sun.nio.ch.SelectorImpl.select(SelectorImpl.java:97) > at > org.apache.hadoop.net.SocketIOWithTimeout$SelectorPool.select(SocketIOWithTimeout.java:336) > at > org.apache.hadoop.net.SocketIOWithTimeout.connect(SocketIOWithTimeout.java:203) > at org.apache.hadoop.net.NetUtils.connect(NetUtils.java:586) > at > org.apache.hadoop.ipc.Client$Connection.setupConnection(Client.java:700) > at > org.apache.hadoop.ipc.Client$Connection.setupIOstreams(Client.java:821) > at org.apache.hadoop.ipc.Client$Connection.access$3800(Client.java:413) > at org.apache.hadoop.ipc.Client.getConnection(Client.java:1645) > at org.apache.hadoop.ipc.Client.call(Client.java:1461) > at org.apache.hadoop.ipc.Client.call(Client.java:1414) > at > org.apache.hadoop.ipc.ProtobufRpcEngine2$Invoker.invoke(ProtobufRpcEngine2.java:234) > at > org.apache.hadoop.ipc.ProtobufRpcEngine2$Invoker.invoke(ProtobufRpcEngine2.java:119) > at com.sun.proxy.$Proxy24.startContainers(Unknown Source) > at > org.apache.hadoop.yarn.api.impl.pb.client.ContainerManagementProtocolPBClientImpl.startContainers(ContainerManagementProtocolPBClientImpl.java:133) > 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.apache.hadoop.io.retry.RetryInvocationHandler.invokeMethod(RetryInvocationHandler.java:431) > at > org.apache.hadoop.io.retry.RetryInvocationHandler$Call.invokeMethod(RetryInvocationHandler.java:166) > at > org.apache.hadoop.io.retry.RetryInvocationHandler$Call.invoke(RetryInvocationHandler.java:158) > at > org.apache.hadoop.io.retry.RetryInvocationHandler$Call.invokeOnce(RetryInvocationHandler.java:96) > at > org.apache.hadoop.io.retry.RetryInvocationHandler.invoke(RetryInvocationHandler.java:362) > at com.sun.proxy.$Proxy25.startContainers(Unknown Source) > at > org.apache.hadoop.yarn.server.nodemanager.containermanager.TestNMProxy.testNMProxyRPCRetry(TestNMProxy.java:167) > 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$1.runReflectiveCall(FrameworkMethod.java:50) > at > org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) > at > org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) > at > org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) > at > org.junit.internal.runners.statements.FailOnTimeout$CallableStatement.call(FailOnTimeout.java:298) > at > org.junit.internal.runners.statements.FailOnTimeout$CallableStatement.call(FailOnTimeout.java:292) > at java.util.concurrent.FutureTask.run(FutureTask.java:266) > at java.lang.Thread.run(Thread.java:748) > [INFO] > [INFO] Results: > [INFO] > [ERROR] Errors: > [ERROR] TestNMProxy.testNMProxyRPCRetry:167 » TestTimedOut test timed out > after 20000 ... > {code} -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
